Sometimes pidgin stops drawing for me.

The program still runs.  I noticed that even tho' I can't see it,
I can send IM's to my contacts.  They get the text but the window
stays blank (just the widget background color).

Sometimes I've had to restart X.  I've never had to reboot the
computer to get this fixed.

I'm using naked openbox (no desktop environment).
