Unfortunately, the behavior occured just once after I last updated Emacs to the new timer-based stuff, and I did not debug it then since it just made me shrug and say "same bug as before". So the frequency of that occurence seemingly has dropped sharply, at least. I am rather sure, however, that I encountered it this one time after recompiling Emacs. If I manage to have it happen again, I'll sic the debugger on it, something I should have done the first time. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
