Mouse Delays

Yesterday on my post about mice, I mentioned that I was still seeing a little problem with my new mouse:

For some strange reason I haven't been able to figure out, however, I'm still seeing moments where the mouse will stop responding (stop moving) for short periods of time.

It now appears that I found the cause of the problem: I had the wireless receiver of the mouse connected to one of the USB ports on my Dell UltraSharp 2208WFP monitor.

As soon as I plugged the receiver directly into one of the USB on my latop, the problem went away. It's not all that surprising, since I had already noticed problems before when I tried Natural Ergonomic Keyboard 4000 connected to the monitor: keys would randomly repeat in very inconvenient ways!

It would appear then that either the USB ports on my monitor have some issues that cause devices to function incorrectly (possibly a timing problem?), but not sure if it's a general problem with this monitor line or if it's a problem with my unit specifically.
