Paint Shop Pro :: Brushes Freeze When Trying To Access In X5?

I have Windows 7 64 bit and PSP x5. Everytime I try to access my brushes, it freezes and the drop down menu won't open to select a brush. If I play with it for an hour or so it will finally come down for a second and I have to select quickly before it closes again. I have lots of memory and hard drive space. I've uninstalled KB2670838 windows update, as another forum suggested for general x5 freezes. I deleted all the brushed from the program file and made a separate folder and pointed XP to it in the file locations. The same thing happened with my tubes, but after continually trying to open them several times, it finally opened and from that point on it worked, not so with the brushes which I need to use in my work.I don't want to have to uninstall and reinstall, it took so long to get all the plugins added and working to have to do that again.
