Thanks.
I'd already stumbled through just about every XCom/Dosbox repository around trying to get this running. I'm all set at the moment, except that the cursor just doesn't work properly.

It's the whole 'absolute' versus 'relative' mousing coordinates thing.

That first tabletPC link you sent was close, but their work-around was ms tabletXP-specific. I was kinda hoping I didn't have to crack open the development tools and try to patch things myself. =/
