I run version 7.12 mostly just because I hadn't needed anything newer....but in its "Control Panel" there are some touch settings that you might want to play with.
Look for Microtouch in your programs list.
Set it to DRAWING for sure if you have that option.
And then play with some of the double click options to your liking.
As for Win7 .... you're just going to have to give it a try.
(I don't use it for anything, so never tried any drivers for it)
