asus laptop hangs when sony ericsson phone is near by!?

i have an asus laptop and a sony ericsson w580i mobile buzz.
recently i used the bluetooth to conveying files between my computer n the mobile.
now i find that the computer hangs whenever the buzz is beside it. i turned off my buzz and the laptop worked well but once i switch on the buzz my laptop hangs. (the cause of the hangs is certainly due to my buzz)

i’m using windows vista premium and i cant install my buzz’s driver although it says that it is compatible with windows vista.. i reflect its a compatibility problem..

thanks for your time..
