DC 17, Windows 7. For 10 years, only occasional use of DC 17. Now problems with new files created for old project. In the beginning everything worked and then after modifying things these problem:
Opened file, did some lines, inserted symbols, edited some symbols and then the drawing receded into a point. Zoom extents works, Page up, down works, Home works. I can edit/add entities but using mouse wheel to zoom either in/out collapses drawing to that tiny point. Saving file and reopening results in same result. Exiting DC and restarting allows new editing but not for long before the same behavior restarts. And mix in a DC crash or 2.
HELP! I have tried to repeat the steps and locate the precipitating instant but cannot narrow anything down.
TIA
