Windows 7: Handwriting functions no longer working

So recently, I just noticed that I can no longer use any handwriting functions of Windows. And I mean, all of them.



Example, when I use windows live messenger, I clicked the handwriting icon because I Was gonna draw something for a contact obviously, put my mouse inside, and no dot appeared. Clicking yielded no results. And then I opened OneNote, and other various handwriting enabled applications through windows, and nothing would work. Paint and all that worked and stuff, but it was just these handwriting applications not working.

I can't seem to figure out what's the issue, I've tried uninstalling and reinstalling the Tablet PC optional components and such.

Plus, on the flipside, I can no longer use the snipping tool. It says "The Snipping Tool is not working on your computer right now." I think there's a correlation between that and my handwriting functions not working.

ANy suggestions?

Alright, so here's an update

I disabled UAC all the way through. It never comes up, so effectively, everything is administrator approved. My snipping tool and handwriting functions are working correctly.

What gives?
