Windows 7: Bluetooth mouse lagging out

I have a Microsoft Intellimouse Bluetooth connected to an usb bluetooth dongle using win 7 drivers.

Mouse works perfect för 30-60 minutes but then starts to lag out and move very erratic. After a reboot the mouse is back in perfect shape. Its not a signal issue since its always perfect right after reboot and signal strenght is displayed as strong.



Once starting to lag it wont go back until reboot. Any ideas?

It makes it sound as if it's clockwork LOL...

Normally either these work, or they don't. There's not much 'inbetween' so to speak, all I can think of is that there could be something else conflicting with the mouse, which could either be an IRQ issue, or a 2.4Ghz band/wifi issue.

The obvious thing I haven't said is whether you could be rolling along a ball of fluff in the lens aperture, or you haven't cleaned the optical lens in an eon or so, both of which would have a negative impact upon behaviour...

Otherwise perhaps it's batteries are tired, or it is simply now treading the road to dereliction, nearing the end of its natural life...

Meaning I should just buy a new one?

Well, I'm not sure I said as much... however you can get more reliable service from a wireless USB mouse without any pairing snags - and what I suggested you do with your BT mouse was check for fluff, IRQ conflicts, and ensure you haven't sited the dongle within too close a distance to anything else using the 2.4Ghz band...
