--- Comment #6 from Nicolas Ford diffyq@gmail.com 2008-04-29 21:38:23 --- This is happening to me too, exactly as described, with 0.9.59. For a while, the phenomenon appeared to be accompanied by the line "fixme:msg:pack_message msg 14 (WM_ERASEBKGND) not supported yet," but when I tried to reproduce it, it didn't come up again.
