I'm working on a new server, and I've started with the sample server
using the CFB code.  I've got it up and running, but I'm having a
bit of a problem with backing store.

If I run twm and xlogo and pop-up the twm menu over top of xlogo,
the menu pops up fine and usually pops down fine too, with xlogo
being redrawn from backing store without any expose event.  However,
about one time out of three, when the menu pops down, it leaves a
vertical black line one pixel wide across xlogo where the right
hand edge of the menu was.  Has anyone seen this before and know
what the fix is?  I know, "Use the source, Luke," but I thought I'd
ask before digging in.

(Hummm, maybe I should ask AT&T... ;-)
