Loss of control of current window & Quit command
Operating system version
Description of the issue
Twice in the past week I have been working developing and entering data and the window becomes unresponsive. I can open another window, but there is no mouse clicks or keystrokes work in the frozen window. I can't close that window and I can't quit the application. I had to Force Quit the application, which doesn't seem to have caused any corruption.
Steps to reproduce the problem
The application will work without becoming unresponsive.
