Wireless Mouse Software Update for Mac

i try to install the update but it tells me that this is notbthe latest update and then closes the application. no-where will give me the updated version and cant upload the previous update, My magic mouse is not being recognised. wireless accessories are bought so things can be done with ease. This is nowhere near as easy as it should be. an someone lead me to the latest update plz

after upgrade, i am unable to mount WD drives connected via firewire 800

Is it just me, or does anybody else think it's insane that a mouse driver is 60+ MB in size? I'm sure the new hardware is awesome (I plan to get one), but whatever happened to tight coding? These package sizes (not just this, but everything) has gotten so out of control.

Platform should be changed from Intel to Universal. Just installed on a PPC without problems.

May I safely assume that this upgrade is not for the wireless mouse called Mighty Mouse that came with my machine which has been upgraded to Snow Leopard? Were it not for the picture of the new wireless mouse, I'd sure think this was referring to the old wireless mouse, and you'd figure that an upgrade would apply to the old wireless mouse, but I'm guessing not. Things are not always crystal clear to me. Sorry.
