This looks like a bug in Motif.  Button 2 starts a drag for drag and 
drop, but it seems that menu traversal messes things up so the pointer 
and keyboard is grabbed but never released.  The icon you see is the 
Motif drag and drop icon.  I can reproduce this bug in other Motif 
applications, so it is not an Emacs bug.  But as a workaround I have 
disabled button 2 for the menu bar, please try it.

Thanks,
