Slow Mouse/Keyboard...maybe since last major update?

I'm wondering if anyone has noted any problems with their keyboards/mice since the last major update. I can't seem to figure out the culprit and I was thinking it was this. My mouse pointer skips across the screen at times and the scroll wheel on the mouse isn't always very smooth on the screen. So, considering the scroll wheel is also having problems, I doubt it's just a dirty mouse pad.

I use a Logitech keyboard/mouse, wireless with a unifying receiver.

I have not noticed any problems. Is the firmware on your Logitech equipment updated? You can check this in the Unifying software.

If you move the receiver to a new USB port, and Windows downloads new drivers, does it help solve the issue?
