You're welcome to try, but my gut feeling is that it won't work.  Thanks
for going through all that trouble to debug this!

If XtGrabPointer returns a non-zero value, then it means obtaining the
grab failed.  Exactly which non-zero value does it return?  Do the menus
start working if you comment out the call to "XtGrabPointer" entirely?

The relevant return codes are:

        #define GrabSuccess             0
        #define AlreadyGrabbed          1
        #define GrabInvalidTime         2
        #define GrabNotViewable         3
        #define GrabFrozen              4

Yes, as long as you keep the "bug#" intact.
