mouse scroll?

[jnpoint]

My mouse scroll continues to fall out (does not work in game). I have tried to different mice, but with the same result. Every time I start up, the scroll function works fine, but after 1-2 minutes it doesn't. I use win 7, so the drivers are standard - can't change them.

Any help - maybe a bug?

It's still a problem, but it first start to be a problem after I have played a game for several hours.
