I can't comment on this technically, but the overall effect is lovely. Nice
work!

However, the menu window dragging event loop doesn't work on my machine. I
believe the new event loop exposes a race condition in which the window's frame
information becomes corrupted. If I drag a menu for even just a few seconds, by
the end of the drag the menu is jumping all over the screen.

[side note: I just ran GSTest.app with --GNU-Debug=XSynchronize and the menu
still leapt about, though not quite as much, so it may not be a race
condition.]

I modified XGDragView to use this type of event loop and had the same issue pop
up.

Cheers!

Michael
