Description Jan D. 2004-12-31 21:24:01 UTC 
Compile attached program with Gtk+ 2.6
Run without arguments (turns double buffer off for drawing area),
click on the file menu, and move the pointer so that the other menus
(Edit and Help) are expanded in turn.
Note that the menus are still drawn on the drawing area even after they
are popped down (see attached screen shot).

If run iwth any argument, double buffer is turned on and it works OK.
Also, it works OK with Gtk+ 2.4, regardless of double buffer off or not.

Your expose handler needs to clear to the background... that was
true (though less obvious) for 2.4 as well.
