If you are convinced its a ZA problem, roll back to version 4.5. Version 5
has serious problems-you may have just found another. In any case, ZA 4.5 is
clearly more stable and bug free. To do a clean uninstall follow the
instruction he http://don.hoover.net/uninstall.html. Don't waste your
time on version 5 any more.
