slow thinking corel x3

I am running Vista and have an i7 chip with 3 gigs of ram and a 1 gig video cars...Games fast (according to my Kids) I try and use crel x3 and it is hitchy and slow to react. I have already tried the patch sugested by corel and it did nothing!

 I built this computer because I wanted fast.....I can still think faster than corel reacts!

Help me figure this out and you will be my new hero!
