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.
