Mouse problems

[Octopuss]

Ever since I installed Windows 7, my mouse behaves weird - it's totally random though. Everything is fine, and all of a sudden the cursor pretty much stops moving no matter how much I move with the mouse itself. Often it is just in vertical direction, but that's far from a rule.

Has anyone experienced anything similar?

Plugging it in different USB port doesn't change anything, and nor does reinstalling the whole system.

My Logitech MX400 has a mind of it's own sometimes as well. It was worse in XP though. I just put it down to Logitech's crap hardware, since I don't use SetPoint.

I've got an original MS Intellimouse Explorer 3.0, 7 years old now and very well used, that I've done surgery on several times to replace worn parts in and it still works perfectly.

But my 3 year old Logitech? Not so perfect.

Well, I have Logitech G500. It works well, but just occasionally (sometimes not even once per day, other times several...) goes bananas. I know it was fine in XP and Vista.

Have you had any problems with a single key either suddenly quit working or act like it's stuck down? So far this has only happened while playing games.

In my case, Thief 2, Fallout 3, and Modern Warfare 2 so far.

I know of other people it's happened to in other games, and it's always on Win7.

I think there's a bug in DirectX causing it, because when the game is exited, the problem is gone as well. Sometimes it stops on it's own too.

Could be related to the mouse issue.

Unfortunately it happens outside of games as well.
