I seem to be having problems with Grammarian PRO X windows and sometimes get the spinning beach ball. What should I do?
If the Grammarian preference file gets partially written or damaged, this could cause strange behavior. Quit Grammarian PRO X, find the Grammarian preferences file in the Users/Library/Preferences folder, and throw this file into the trash. The next time Grammarian runs, it’ll build a new preference file.
