I just installed Leopard (with upgrade option) on my SR MBP yesterday. The weird thing is that my Apple wireless mighty mouse has stopped working twice in the past 24 hours. It came out of nowhere. when it stopped working, i tried to open bluetooth assistant and it did not respond, then i tried to restart my MBP and it wont restart. I'm not sure if Leopard's the one to blame as i am pretty new to the mac world but this has never happened to me when i was using 10.4 since July. Is anyone using Leopard experiencing problems with wireless mighty mouse? Any suggestions will be appreciated.
