21.5b3/gtk: bad redisplay after progress bars

sometimes, but not always, after the progress bar is done the buffers are not properly redisplayed. Instead an orphaned buffer is left behind. here is a screenshot: http://folks.astrian.net/godzilla/xemacs-redisplay.jpg things to note: 1.) orphan at bottom (display of .ddd/.dia). this orphan disspears only after i scroll through the (top) buffer. 2.) ghost left in mini-buffer: you can see part of a "Fontifying godzilla" remains in the mini-buffer. This is the first time i have compiled with gtk/gnome support. don't know if this problem occured previously. les schaffer p.s. occasionally i see on stderr: Hey, change the tab-focus you boob... uhhh, could someone be more specific about whats wrong????
