[Newbies] Stopping a debug-window loop

[Blake]

OK, I've got a debug window popping up over and over again.

I can Alt+. but that pops up a user interrupt window which is immediately  
plastered over by another of the same debug window.

I tried Ctrl+C as well, based on advice from Stepehn Ducasse's book.  
Nothing there.

In the past I've just closed the Squeak window, but it's really tiresome  
having to redo all the work since the last save. (It only matters a little  
how much work. It's tiresome on principle.)

Can anything be done to stop this?
