Hey,
You can check
my forum posting which is just a little farther down in the list... It sounds like the same problem on the same hardware. We're waiting for a driver update that hopefully fixes this problem that many users seem to have. There is a suggestion in the post that resolves the flickering, though it's at the expense of some added lag. That being said, I have no problems with my wireless mouse, either with the receiver directly connected to the docking station (rear ports) or via a USB hub.
