Graphics Tablet with Dual Monitors

Hello,

I have just bought an Aiptek Slim Tablet to replace my old one which didn't have Vista drivers. The trouble is that I have a dual monitor setup and I can't restrict the tablet to one screen. This means that if I have Photoshop open in one monitor I can only use half of the tablet to draw on.

Does anyone know any way to fix this/work around it (other than switching to single-monitor mode everytime I want to use it - annoying as I usually have the image/whatever I'm working from open on the second monitor)?

I saw an old post in another forum suggesting that I change the PANEL_WIDTH parameter in the .ini file (aiptbl.ini) but mine does not have this option... I guess because that referred to an older version of the driver.

Any help is very much appreciated!
