[AccessD] Table/Query Shortcut Menu Disappeared

Hi all,
	I'm having a strange problem with Access 2000 SR-3, Windows 2000
Pro SP-3. I can no longer get the shortcut menu to popup when
right-clicking on a table or query in the database window of any
database using Access 2000. Right-Clicking selects the Table/Query but
does not popup a menu. The shortcut menu works for
forms/reports/macros/modules, just not for tables/queries. I've tried
deselecting/reselecting Allow Default Shortcut Menus but that had no
effect.  I've tried repairing and deleting and re-installing Office but
it still does not work correctly. I've deleted all Add-ins in case that
was the problem but nothing seems to fix this. I also have Access 97 and
XP loaded on the same machine and the shortcuts work correctly using
those, just not in Access 2000. Everything else seems to work correctly,
including custom shortcut menus for some forms. 
	Has anyone else had this problem and is there a solution? It
worked correctly last week and I don't think I've installed anything
since. 
	Any and all suggestions would be welcome.

Thanks,

James Barash
