Thor....get a mac,lol
silly PC people and their problems, iTunes rules all,
A bid rip would be a possibility, but spyware can never really be removed if the new Kazza software has taken effect. What kazza does is build the spyware RIGHT INTO THE PROGRAM on the new version i believe. You cannot delete it, and if you use a program to block it, kazza can tell because the outgoing signal doesn't get to their mainframe, then kazza doesn't work. Either way, i use a mac, so i have none of those problems.
If it's a wireless mouse, that may be a problem with something interferring it or to check the batts. Run a norton check and see what programs are taking up the most proccesor speed.
If you run backwards, do you gain weight?
