Mighty Mouse

I noticed a weird issue with my blue tooth mighty mouse and my 13in mac book pro..basically when my wireless connection ramps up like when i am downloading a file my mighty mouse starts to lag bad and becomes very unresponsive..i notices this only happens when my macbook is in clamshell mode with a external monitor if i open up the lid the mighty moouse works fine again...my guess its a issue with my wireless router using a 2.4ghz connection but i could be wrong what do you guys think?

Mine gets a bit odd at times when the battery is getting low in charge, a fresh set of rechargeables seems to things.

A lot of people have issues with Apple's wireless mice in general. Some of these issues extend to the new Magic Mouse.

I don't have experience with Bluetooth mice, but I agree with Collin. Change the batteries with some fresh ones and see what happens.

I doubt your wireless connection is the culprit but it is within the realm of possibility.
