My drawings unexpectedly close in the middle of work. This happened when I was using DataCAD 22 and now with DataCAD 23. Is this a problem with the program or my computer, If a problem with the program any ideas on how to fix it. If its my computer I may need to get a new one. I don't have this problem with any other program on my computer.
Any help is greatly appreciated.
