MacBook + Bluetooth + Mighty Mouse = Problem

Hi, I`ve recently begun having problems with my bluetooth Mighty mouse, once in a while i get an onscreen message - ''connection lost'', the bluetooth symbol on top of the screen has ''~'' over itself, and when i click it, it says ''bluetooth: not available''. usually a minute later bluetooth turns on, establishes connection with the mouse and everything is ok again for the next couple hours. Could anybody tell me what is going on? Any feedback is appreciated, thanks in advance!

mod, wrong forum, please delete the thread

Nope, this deals with a Mighty Mouse so this is the correct forum.
