2.6.8-p2 on Snow Leopard - if I click Cmd-` (backtick) Gimp immediately stops responding to mouse movement and and keystrokes. The only way to get it back is to kill it (losing all the data). Can anyone else replicate this or is it a weirdness on my machine?
Cmd-` is the X shortcut for "Cycle Through Windows". Oddly, selecting the item from the X menu works as expected - only the shortcut causes the lock-up.
