Logitec V270 bluetooth mouse freezes
I found no solution but plenty of similar complaints on the V270 on other than just Vista machines. I will suggest finding another model mouse and check it for Vista compatibility before buying.
I am using a Logitech M-RBB_DEL4 mouse made for Dell, it's bluetooth and works flawlessly on my XP machine along with the keyboard it came with. I will try the one I just ordered on my Vista machine when the BT Keyboard and Mouse arrive.
