I recently bought a new laptop and installed the driver needed for my Wacom tablet. The first thing I noticed was my inability to draw a smooth line in Flash. Even though the pen is being held still, the cursor shakes slightly and drifts a little. The only reason i can think would be the wireless usb mouse I have on the same computer.

I am operating under Windows Vista SP1 on a Toshiba laptop with 3gb of ram and 200 gb of memory. I have a wireless optical mouse in use at the same time. I am drawing in Flash MX 2004. The pen driver i downloaded is the "new" version from the Wacom website.
(I don't think Vista is the problem, since I was using Vista on my desktop under the same SP and didn't have any problems.)
