[R-SIG-Mac] R.app spontaneously switching windows during editing

[John Helly]

Aloha.

Apparently since I switched to Big Sur, R has begun spontaneously 
switching the active window from console to editor back and forth for no 
obvious reason.  This disrupts editing and has almost destroyed whole 
editing files due to the deletion of highlighted lines (a different 
behavior that has always been dangerous but is exacerbated by the 
window-switching).

I've looked at the default settings in the Preferences and can't see or 
change anything that seems to affect this behavior. I've tried turning 
off everything that might be doing it (e.g., matching delimiters) and I 
can't find anything or anyone else that complains about this. Am I the 
only one?

Any suggestions for debugging this would be welcome.  sessionInfo below.

J. Helly.
