Unable to click anything due to stuck touchscreen state

At least several times a day (most commonly after resuming from suspend), I'm unable to click on anything with my mouse, use Alt-Tab, or switch workspaces. After tapping my touchscreen the problem goes away.

This has been happening since I purchased this computer and installed oneiric.

I suspect the touchscreen is getting stuck in a bad state (for example a mouse-down state), and as a result the only thing the trackpad can do is move the mouse.

(I ran ubuntu-bug while in one of these states, so if the logs show anything it should be there)
