Is ID 2021 incompatible with the Mojave system on the MAC?
1. It won't open
2. It will not open documents I worked on previously
3. It will not respond to force quit
4. It vanishes from the screen but is still listed as open in the force quit window but won't quit
I have repeatedly uninstalled the entire program, run a computer cleaning program to delete preferences (no, it won't work to hold down the various keys) and reinstalled. This gives me a brief respite to work on documents, but when I try to quit it won't.
