I've had the same problem here in porting Motif 2.1->Lesstif, but didn't
have time to test for work arounds.
Glad it's not just my system. :)

We've come up with a problem in Lesstif.
In our software we have a menu that is popped up via a right mouse
button click.
If the user clicks *and holds* the right mouse button and drags down
to a cascading menu item, the submenu pops up to the right and they
can drag over to it and select something off the submenu.
If the user right clicks *and lets go* the menu stays open (as
expected). If they then click (left or right, doesn't matter) on the
cascading menu item, the submenu pops up to the right, but the parent
menu has grabbed the pointer or something because you can't click on
the submenu.
The code looks like...
m_widget = XmCreatePopupMenu(parent, "popup", args, n);
// [ calls a function which adds all the menu items here ]
XButtonPressedEvent event;
memset(&event,0,sizeof(event));
event.type = ButtonPress;
event.display = XtDisplay(ctrl.GetWidget());
event.window = XtWindow(ctrl.GetWidget());
unsigned int buttons;
XQueryPointer(event.display, event.window, &event.root,
&event.subwindow, &event.x_root, &event.y_root, &event.x, &event.y,
&buttons);
XmMenuPosition(m_widget,&event);
XtManageChild(m_widget)
MxWaitForUnmap(m_widget); // <- a function of ours that does an event
loop until the given widget is unmapped
The author of this code tells me he tried several other ways of
popping up the menu with no luck.
