I am finding intermittent problems with office for mac. Mostly everything is running ok but the odd time say one in ten times of opening Word,Excel,Powerpoint when I try to shut them down they just sit there with the beachball of death spinning. Everything else works fine but I end up having to force quit these applications! I am running a MBP 2GHZ 2GB RAM 100GB @7200RPM. Anyone have any ideas??
