My Bluetooth mouse will occasionally freeze for a second, then replay my movements delayed by a second. This "delayed playback" behavior lasts several seconds, consistently lagging a second behind, before the displayed position suddenly fast-forwards to my current mouse position.

This can happen a couple times a day - the rest of the time the mouse is perfectly responsive.

I haven't noticed any system activity that correlates with the delays (such as heavy I/O). Also, the mouse has fresh batteries.

I never saw this when using the mouse with the old machine I had - I've only seen it on my new laptop.

How can I go about troubleshooting or preventing this?

Check the Event Log for Bluetooth issues. Try to install the same driver version on both machines and see if the issue persists.

Bluetooth uses a wireless technology called FHSS (Frequency hopping spread spectrum), meaning any interference should be intermittent because it has the ability to "hop" frequencies. Bluetooth operates in the 2.4Ghz frequency if I recall correctly, so newer cordless phones and other wireless devices could cause intermittent interruption, although very brief.

You can try repositioning your bluetooth receiver. If you need, find an USB extension cord to help reposition the receiver. I would point it straight up if possible. Also would help if you provided model and brand of the mouse. Trying different drivers wouldn't hurt either.

The Bluetooth receiver is in the laptop, which is 12 inches from my mouse. The mouse is a Dell DH956. The drivers I'm using are the standard Windows 7 drivers. –  mskfisher Feb 2 '11 at 17:52
