Disable auto-hide menus on tablet PC?

I absolutely love this game so far, it runs and looks great on my Dell Latitude XT tablet PC. The gameplay of the game also lends itself perfectly to pen or touch usage, since it's just a point and click game. The only issue is that it's impossible to get the pen or touch close enough to the edge of the screen to make the menus appear. Is there any way it's possible to disable the auto-hide feature, or maybe give a slightly larger tolerance for detecting when the mouse is at the edge of the screen? If I want to use the pen now, I have to use the 80% version, which is a shame since 100% is the actual resolution of my display.
