And even if I click on an open window of a compiled document, only that window is accessible. Using Command-` to cycle through open windows doesn't work, nor does Command-1 to switch to the source of the open PDF. Even when the top menu bar appears, it doesn't work properly: clicking on a menu just causes the top element to be greyed but the menu itself doesn't drop down. Clicking again causes the menu to appear only to instantly disappear again. The only thing that reliably brings the application back to partially normal behaviour is to start opening a file using Command-O and then cancelling the open. This brings all the open windows back and then everything works almost as normal except menu item choosing which is still wonky. I thought this might have had something to do with tabbed vs. !

This is a recurring problem and initially things do work so restarting isn’t really a solution. I wonder if certain OS level things now work differently with Ventura and are causing problems with older versions of the OS.
