No mouse cursor

Edit: Never mind, I found the offending problem program that triggered this (Pando Media Booster) and removed it. Mouse is back thankfully.

Is there any indication this has happened to anyone besides you? If not, I suggest it was not the game but something about your computer - despite the apparent 'timing'. Give it a day or so and see if anyone else comes along with the same problem. If so, try to find common factors. If not, it may be just you.

I'll also state the blindingly obvious - it's certainly not affecting everyone, or even a large number.
