You know the skritter option to use the Wacom plug-in? This has a nasty side effect for me that as soon as I hit the mains skritter app, my size-of-screen is reset to whole tablet.

So I turned it off and it's fine. Now I've had it off for awhile, I'm not sure why I ever had it on? There's supposed to be some sort of pressure feedback right, not so that I ever really noticed...

Yeah, it can be weird, especially in certain browsers. What it does is make the thickness of your squigs dependent on how hard you're pressing rather than how quickly you're writing. Makes it look prettier. It's just cosmetic, so by all means just turn it off if it be triflin'.
