Something went wrong with your posting -- it came out completely in 

I think I have found what was wrong with the editor windows.  There were 
two problems:

  - a variable was sometimes uninitialized.  I've fixed this in R-devel 
(though it won't be downloadable for a while).  I had hoped this was 
enough, but it wasn't.

  - the script editor window duplicates some menu items from the main 
window, but unfortunately in doing so it overwrites some pointers to 
those items.  When the script editor is closed, the pointers become 
invalid, and you may crash.

The second fix will require more extensive work, but I should get it 
done today.
