Has anybody ever experienced this before?
Has anybody got a clue how to fix it?

Somehow something has happened to my Excel2003/PC (running on XP) so
that I can go into the Immediate window and run the first line below,
and then if I question what the state of the screenupdating is
immediately afterward I've set it to False I get a result of True !!

Application.ScreenUpdating =False
?Application.ScreenUpdating
True


Any help greatly appreciated,
Regards
Jason.
