This problem has been fixed in CVS head, but not in 21.3.  But the problem does 
only occur if ALT, Ctrl or Mod is pressed as the menu selection is done, not Shift.

So, Ctrl-Mouse-1 and then select *Message* with Ctrl pressed does not switch to 
*Messages* in 21.2 and 21.3.

Emacs is not even involved in posting cascade menus for the menu bar, it is all 
taken care of by the toolkit (Motif).  Maybe some X resource or the Motif 
version changed?
