Hi, Mark. No, I hadn't applied the service packs. However, I went and downloaded the latest version from Adept, and applied it, and checked that the S/N had a C after it (it did), and tested my demo worksheet, and the problem still manifested exactly the same. The fact that it is completely reproducible is rather unusual IME and makes me wonder if it might actually be useful to Mathsoft, depending of course on whether it still manifests in later versions, and whether the equation editor has been completely rewritten for v13 as it is supposed to have been. I've never posted a worksheet to the forum before. Would you or anyone else be interested to see if my demo "works" on other machines and versions? If so, do I just attach and post?

Hi all, The red face is all mine, not Paul's. His red thing is a herring i.e. my original posting that really did take 3 days to get back to me, and caused me to suspect a server problem when my alleged follow-up with attachment still hadn't got back to me 5 days later. Turns out the reason was that I didn't post it, I emailed it direct to Mark Smith - who then replied via the list. Hence my firm belief that I had posted it in the first place. However, I hadn't, so (belatedly) here it is. And at least now I know why list postings sometimes resemble buses in the way they all arrive at once. Andy OK, here we go. Worksheet attached, the file name is most of the instructions! I haven't experimented with how much of the worksheet I can chop out and still have the bug exhibit itself, life's too short. So... 1) Open worksheet, scroll to bottom. In the very last expression, you will see an unoccupied placeholder. Click it to select it with the blue right-angle thingy, hit Delete on keyboard. Wave a quick goodbye to Mathcad. 2) I just tried an alternative Delete method. After clicking placeholder to select it with the blue right-angle thing, I tried carefully dragging to select it the alternative way i.e. so it is covered with the black box thing (I did this because when I previously reported weird copy and paste behaviour in the editor, I was advised to use the black box method rather than the blue right-angle method).

Andy, Yes, I did repeat your dilemma in MathCAD 12, and I was amazed how fast MathCAD went away.

"I was amazed how fast MathCAD went away" :-) Unnerving, isn't it? So it happens in Mathcad 12 too, eh? Hmmm. What OS are you using? Interesting that you used Backspace instead of Delete. That would never have occurred to me. I tried both flavours of blue right-angled cursor with Backspace and Delete. Backspace works with both flavours. You've seen the consequence of using Delete with one flavour... and as I posted in reply to Mark Smith, trying to use Delete with the other flavour just "reverses flavour polarity" for me (his mileage varied, evidently). It's been so long since I had to refer to the manual that you've got me wondering now if Backspace is the way I'm supposed to Delete things (albeit even if it is, hitting Delete shouldn't have such catastrophic results). I'm going to check.

Andy, ...and it went away... We're using XP Professional, Version 5.1.2600 Computer is a Pentium 4, 3.40 GHz, 1Gig of RAM We're an Engineering firm trying to keep up... _____ From: "Andy.Spragg" "mailto:Andy.Spragg" Sent: Tuesday, October 04, 2005 5:01 AM To: Mathcad Discussion List Subject: [mathcad] RE: Weird editor bugs (again) "I was amazed how fast MathCAD went away" :-) Unnerving, isn't it? So it happens in Mathcad 12 too, eh? Hmmm. What OS are you using? Interesting that you used Backspace instead of Delete. That would never have occurred to me. I tried both flavours of blue right-angled cursor with Backspace and Delete. Backspace works with both flavours. You've seen the consequence of using Delete with one flavour... and as I posted in reply to Mark Smith, trying to use Delete with the other flavour just "reverses flavour polarity" for me (his mileage varied, evidently). It's been so long since I had to refer to the manual that you've got me wondering now if Backspace is the way I'm supposed to Delete things (albeit even if it is, hitting Delete shouldn't have such catastrophic results). I'm going to check. Andy "Troyer, Rod" "RTroyer" 03/10/2005 18:35 Please respond to "mathcad" To Mathcad Discussion List "mathcad" cc Subject [mathcad] RE: Weird editor bugs (again)

Rod (cc Mathsoft, for info and [hopefully] action; please see thread on Adept Scientific's Mathcad discussion forum) "?and it went away?". ? . Do you mean you can't reproduce the symptom now? Or are you just referring to Mathcad's amazing disappearing act? I've checked the manual now, and it seems Backspace and Delete are partners in crime (I probably use Backspace as well as Delete when editing without even being conscious of doing so now). In summary, it seems like Backspace deletes to the left of the vertical bar, Delete deletes to the right, and repetition of either one will end up equivalent to a single one of same after a drag-select. So according to how I read the manual, what should happen in the worksheet I posted, when I click the placeholder to select it with the editing lines, with vertical bar to the left, and hit Delete, is that the editing lines should change to a drag-select region, and hitting Delete again should delete the placeholder. However, the (intended) rules seem to be slightly different for placeholders than they do for expressions. As already pointed out, the deletion process works if changed so that the vertical line is to the right and Backspace is used instead; the first Backspace deletes the preceding operator and replaces it with an operator placeholder, and the second Backspace deletes both placeholders together. So it works, but not exactly how the manual implies it ought to work (or rather how I infer it ought to work, given the manual only talks about deleting expressions and does not explicitly mention placeholders). This would imply that hitting Delete is indeed a legitimate thing to do, and that doing so ought to replace the following operator with a placeholder, and doing it again ought to delete both placeholders together. But no. It seems to open up a black hole and delete Mathcad from memory completely. Now that's what I call a bug :-) Andy **************************************************************** Any opinions expressed in this email are those of the individual and not necessarily of RHM plc and/or any of its subsidiaries.

Andy, The symptoms continue, I was just referring to the thread topic. Obviously a bug has been identified. Unfortunately when I beta tested version 13, this phenomenon was not one I checked out. Possibly and hopefully someone else caught it and it will cease to exist in version 13. To those actually at Mathsoft - any comments? _____ From: "Andy.Spragg" "mailto:Andy.Spragg" Sent: Wednesday, October 05, 2005 9:47 AM To: Mathcad Discussion List Cc: "support" Subject: [mathcad] RE: Weird editor bugs (again) Rod (cc Mathsoft, for info and [hopefully] action; please see thread on Adept Scientific's Mathcad discussion forum) "...and it went away...". ? .

Hi Andy, yes, we've been following this, and yes, it's repeatable in version 13. It doesn't seem to be just any old placeholder, or even just any old placeholder in a matrix. But it's a logged bug now, so we'll get it. Wierd.
