Excel or something else is taking so much resources that
Windows can't paint the screen properly.

Hi hope someone can help. I have a progarm with 1 userform, it was
working fine but all of a sudden when the form is loaded the screen
just goes white, all you can see is the userform name bar at the top,
anyone got any ideas like i say it was working fine, this just happened
overnight.
