logitech wireless mouse acting funny...

speciifcally, I can't zoom in anymore with the wheel.used to work fine but i ahvent played for a seriously long time and when I came back....wow....the changes....green weapons everywhere...lol....i'm even thinking about just starting a whole new character. I dont have any of the new campaigns.....factions etc.....advice?

Want game advide, theres other threads for that, the mouse, though...
1.Which model is it?
2.How old is it?
3.Tried a driver update?
4.GENTLY wipe bottom of mouse with a SOFT cloth. DO NOT "scrub" it, just a light brush, the lens may be obstructed by dust
5.Check this link http://www.rebol.net/article/0213.html see if it helps any.
6.Check knowledgebase at Logitechs site, see what you find
7.Contact Logitech support
Thats all for now, let us know how it goes

Logitech has a support site and forum for this, you know?
