I had the same problem(in tf2 too ), Logitech replaced it free of charge two times, the first one had the same issues, now this one works like a charm.Mad Decent said:Ohhhh man, Good luck with that.. I had that mouse for 2 days before I returned it. The thing is soo crappy. The signal cuts out like every 5mins and your pointer doesnt do shit until you shake the damn mouse.
Seemed to always happen in the middle of firefights in TF2 :lol
Go buy yourself a G9 mouse... [IMG ]http://www.tomsgames.com/us/picturegalleries/20070810/g9_1.jpg[/IMG]
Logitech's support is amazing
