Summary: right mouse button sensitive to modifiers
Initial Comment:
The right mouse button is not recognized if numlock or caps-lock are set, nor
if ctrl, shift, or alt are present. This was observed on an X11 server on
Mandriva 2008.1 using either a static binary or a newly built dynamic binary
linked to openmotif 2.3.0. However, the statically linked version that comes
with Mandriva, which is linked to lesstif 2.1, is NOT sensitive to the state of
the num lock and caps lock.

Well, using xev the modifiers are between 1 and 10 hex, but the primary
bit patterns for state are 0x (for button down) and 400x (for button
release). I don't know where this chunk of code is, but something like
this would implement the desired logic:
if ( event == BUTTON3) {
if(state & 0x400){ /* button 3 release action */ }
else { /* button 3 press action */ }
}
Of course this assumes that there is a place in the code now where "event"
and "state" are available in this form. Perhaps with the callbacks in
Motif this is an invalid assumption.

This is a pretty good observation. It's is a bug as old as time in the
original Motif. We had tried to work around it in the past, but the
workaround could cause the X server to hang (a grab without an ungrab) and
that was unacceptable. A better workaround would help.
