Your code fragments didn't indicate which interface you are using to actually
do the popup.  Some types of popups "grab" keyboard events, meaning, any
keyboard input to the application will be redirected to the popup.  
Read section 5.4 of the X Intrinsics manual, "Mapping a Pop-Up Widget".

Wrong number of arguments, and type mismatch on argument 3, for an action
procedure.

Unless you are implementing a set of popup menus (in which case you 
probably *would* want to do an exclusive grab of keyboard events)
the ICCCCM recommends using transientShellWidgetClass, not override.
