Magic Mouse stalling in 10.7.3 (combo)

Yep

I'm on 10.7.3 and use Magic Mouse and sometimes the mouse is fine, but right now it's like the mouse pointer weighs 100lb. I have to move it 10x further physically to get it to move an inch on the screen. I have two Magic Mouse and it does it for both and is not related to battery voltage. They screwed up something in .3

 

I have different symptoms, but yes, something is not right. This may be a Bluetooth issue i general or specific to the "Magic" mouse. I suspect the former, 'cause I cannot pair an older Apple Mouse with this machine no matter how many times I try (same mouse works fine with a newer Mac mini 2011).
Sometimes (about 20%?) of the time when waking my 2009 MBP from sleep, opening the lid, the mouse pointer will not respond. The bluetooth pull down menu says the mouse is connected, but it is DOA. If I "disconnect" and then "Connect," I get a "revived" Magic Mouse.
Apple has some serious issues to deal with in Lion, even considering that it is still in the early stages at 10.7.3!

 

too much relying on magic to work to little on bluetooth it seems!

 

Yes! I have this same problem. I thought my crappy Apple rechargeables had finally given out... Alas, it seems to be permanent problem. I applied the combo update as well. My computer will just lose connectivity with the mouse. I haven't been able to figure out what gets it to start working again. It just randomly does. My bt keyboard has had no problems.
