When you installed it did you specify XP Compatibility mode? Also sometimes if you right click on the program shortcut and select one of the XP choices in the Compatibility Tab it will work better. I was surprised my trusty rusty old XP scanner worked on Windows 7 when I installed the software using XP compatibility mode. No more booting to XP just to do a scan.

To avoid a lot of Q & A about your hardware and OS configuration, please click on this link to Edit System Specs
Filling this out, at least partially, will save a lot of time. Another advantage is when posting a new problem, the person answering can just click the My System Specs link in the bottom of your post. No need to search for the information.
If you have multiple systems just indicate that in the System Specs so that we know why many of the fields are blank.
