mouse click causes loss of window focus

[soch]

When I click in the window, it looses focus.

When the OS starts the mouse click work fine. After some time I start seeing this problem.

This is happening on a desktop (not a laptop). I have Kingston Trackball drivers installed by OS.

The only workaround I have found is starting task manager. I had this problem in Vista also. Was hoping Win 7 would have fixed it.

This sounds like a driver problem. Especially since it has the same behaviour in Vista.

Did you mean Kensington? Then maybe this post will help you.
