Im having a terrible problem. I am a very avid user of msn, but just recently (about 1-2 months after windows 7 installed) Ive been getting this terrible lag on it. Typing, opening windows, closing windows, moving mouse. Basically anything that involves the msn interface. My room mate also installled msn and hes getting the problem too. We are both using x64 installation. This lag is terrible and starts up after using msn for a bit and wont go away untill you restart the PC, but it comes back after a few minutes again. Gonna have to go back to XP or VISTA if a patch isnt released. Ive seen other people having the same problem in google.
