Animate Pro is really laggy

I reformatted my computer to windows 7 and install Animate Pro. But I cannot draw on it as it is really laggy. It never use to be when I was on Vista. But ever since I put windows 7 on the program does not work correctly. Why is this? Is it the operating system?

Is there something I can do to sort this out?

First thing to do is go to your desktop, right-click and select Personalize, and switch from Aero theme to Basic.

You will also probably need to download the latest drivers for your graphics card, as your Vista drivers won’t be new enough.

Also download the latest drivers for your tablet.
