wireless mouse loosing conection
I have problems with wireless mouse, frequently loosing connection
iMac, Mac OS X (10.6.8), mouse problems
Apple's build-in bluetooth connection for peripherals isn't all that great.
As a result of this it is possible that your mouse disconnects from time to time. I've experienced through the years, that their signal is indeed very weak.
If this is not an experience threatening problem, I would not worry about it too much.
Another cause of this problem might be your batteries. I myself am unaware of the exact link between batteries and your connection, but googling the internet might provide some insight on the situation.
