Problem defining new variables in Mathcad 15

‌Frequently, my curor position will not accept typing a variable name.  The cursor location is not close to another region.  The location will accept starting new text if I start the text with quotation marks, ".  I have to keep moving the cursor around randomly to get Mathcad 15 to accept the variable name.  I can paste a variable name at the location; I just cannot start typing at the location. I run Mathcad 15 on a PC with Windows 7 Profesional with plenty of memory.  This problem is so frequent that it makes using Mathcad 15 very frustrating.  I only upgraded to 15 because my old Mathcad 6 plus would not install on Windows 7 without running in a virtual XP mode.

I would just go back to 6 plus running in XP mode, but when I eventually have to upgrade to Windows 10 or beyond, I doubt that running in XP mode will be available.

I did not attach a Mathcad file because I did not think the problem could be repeated on another system.  If attaching a file would help, I will be happy to do that.

I have not tried reinstalling Mathcad 15 because I found the initial licensing procedures from PTC to be extremely user unfriendly!  It took many emails back and forth to get it installed.  I fully understand the need to protect software, but the user unfriendliness of their installation procedures and help on their website seemed impenetrable to me at the time.

Thanks for any help.

Re: Problem defining new variables in Mathcad 15

All--

I did the following based on some of the recommendations.  I removed MS Security Essentials and my cleaners.  I installed BITDEFENDER TOTAL SECURITY 2017.  Complete system scans with this robust malware protection software revealed no issues and indicated that my system was clean including no keyboard logging.  I guess MS Security Essentials kept my system clean.  I then made sure my Windows 7 Professional 64 bit was up-to-date.  I also did a repair to Mathcad 15 from Control Panel.  After doing all this, the problem described above remains.  There are still repeatable dead keystroke areas.  I can paste into those areas on Worksheets; however, I cannot start typing in those areas.  The only exception is starting a string with quotes as described above.

Thanks to all for your responses.  I guess I will just have to live with this problem with Mathcad 15 on my particular system.

Re: Problem defining new variables in Mathcad 15

Sorry,

I have used Mathcad from 2.0 to Prime 4 and OS from DOS to Win 10 and first time see this strange problem.

May be I di nit understand something?

Re: Problem defining new variables in Mathcad 15

I'm afraid I have to agree with Valery (with the exception that I may have missed a few versions of Mathcad).

If I understand well, it's almost impossible for you to type the stuff shown below within 20 seconds:

In short: I guess you are the first to report such a problem.

Is it only in mathcad that you experience such problems?

Do you use any out-of-the-ordinary fonts, do you have special sheet format settings?

Is your PC clean (no keyboard logging software...)?

Re: Problem defining new variables in Mathcad 15

Thanks Luc and Valery for your quick responses.

Here is an example of my problem.

MATHCAD KEYBOARD PROBLEM.jpg

I had to move the cursor as shown to get Mathcad 15 to recognize my keystrokes.

Here are a couple of other things to answer some of your questions.:

  1. This is an intermittent problem.  I never know when and where it will show up.
  2. It only happens in Mathcad 15.  I have a multitude of other programs (now called applications by the youngsters Smiley Embarassed)) that do not exhibit this problem.
  3. My fonts are the normal default fonts.  I have not tried changing them.  I will give that a try.
  4. I don't have any special sheet format settings.  I don't really know how to do that.  The problem above is the way Mathcad 15 opens with a blank sheet.
  5. I do not have any keyboard logging software (to my knowledge) on my computer and I clean it more than once a day with two cleaning programs and I run Windows Security Essentials twice a day.
  6. I checked and I still have Mathcad 6+ installed on the Virtual PC which is available on Windows 7 Professional 64 bit.  I don't think my regular system can see that Virtual PC XP mode.  Perhaps I am mistaken.  I guess I can uninstall Mathcad 6+ in that virtual PC mode and see if that makes any difference.  I suspect it will not.

Thanks again for your responses.

Hi Reg Curry,

let me say that "Windows Security Essentials" does not serve anything. You should use a powerful antivirus (Norton), because this is your problem, in my opinion. Even I, in the past, I used that software (S. E.). As time goes on, the bad software attack gets bigger and the computer becomes unusable, it's crazy. In fact, since I installed Norton Security a few years ago, I no longer have such problems.

Greetings

Hi,

I would suggest that you also try other antivirus (at least the best known or the ones that use the banks).

I, for my antivirus, I pay an annual subscription, so I'm quiet. But earlier, using free antivirus, ... wasahell ...

Re: Problem defining new variables in Mathcad 15

Please post a worksheet in which you have this problem.

Which version of Mathcad 15 are you running?

Re: Problem defining new variables in Mathcad 15

Richard--

Here ya go.  The Mathcad file is attached.  Also, a couple of images: (1) Mathcad 15 Version and (2) image file of where the dead keyboard zones are in the attached Mathcad file.  I doubt they will replicate on your system; nevertheless, here it is.  Thanks.

Re: Problem defining new variables in Mathcad 15

Well, M045 is the latest release, and you are correct that the dead zones do not replicate on my system.

I have never heard of this problem before, and I don't think it's really a Mathcad problem. There's something else on your PC that is causing this, but I have no idea what that might be.
