Hi Priscilla. I had a similar problem with a copy of Corel Painter and PSP a number of years ago although this was with windows XP. The problem turned out to be outdated dirvers for my old Wacom tablet, are you using a Wacom or other make of tablet and can you check that the drivers are up to date ?
Other suggestions would be to uninstall the update and see if the programmes work again.
Do a full virus scan.
Do a disc cleanup and de-frag.
Hope this is of some help
James
