I bought a brand new wireless optical mouse yesterday to replace my broke-down corded optical mouse. And...uh....I'm scurred! Holy shit that thing is hypersensitive - I was all over my screen last night. I dunno what to do. I can't turn it down. I played Lineage last night and because I'm having a hard time adjusting to the mouse - I died.... TWICE LMAO! The mouse is 1600 dpi, not the normal 400 or even 800 and I got a new pad and well, I better get use to this bitch before I die some more - agh!!!!
