Hi there,
I wonder if it is legal to construct a Motif menubar such that some of
the cascade buttons don't have any pulldown menu and command button(s)
as children?  That is, I'd like to set it up such that a callback
routine is attached to the cascade button, rather than to the command
button(s) inside the pulldown menu, as is usually done.  I tried to do
some but ran into some problem :(

The callback triggered by the cascade button performs some Xlib
operations and then pops up a widget, asking user for a mouse button
click.  The problem I'm experiencing is that instead of 1 mouse button
click I need to actually click TWICE to get the thing thru.  I suspect
this is because my cascade button doesn't have any command button(s) as
children, therefore it is still waiting for the xtra mouse button
release event that is usually supplied with clicking on a  command
button inside the pulldown.  I tried to "simulate" this xtra mouse
button event (via XSendEvent) but it didn't work (the program died) -
either because Motif doesn't like XSendEvent or I wasn't doing it right.

Does any know anything about this?  Did anyone try constructing
attaching callbacks to cascade buttons rather than to command buttons?  
Any pointer will be appreciated!
