Check out whether you are running 32 or 64 bits.If you are running Windows at 64 bits, you may not have enough memory to actually manage it. 4 gigs of RAM is the norm for 64 bit installations. This is more likely if you upgraded and didn't buy your computer with 7 preloaded, but you should have gotten a caution message during installation if that was the case.

Go to start, computer, and then system properties. Then look at whether you are running X64 edition. If you are running x64 and don't have enough memory or a fast enough chip, that can create problems. That usually takes the form of crashes during games and other graphic intensive programs. If that is the case, you might have to change your Windows installation.

Make sure that you go to Microsoft update advisor and Broderbund's printmaster updates to make sure you have the latest drivers. Usually, if you go to help in the program menu there is a way to update automatically. It may be under about or something like that. Printmaster was designed to work at 32 bits, but most programs will run on 64.

Hope this helps, leave comments if you have more questions.
