If I decrease/increase mouse sensitivity in Window's "Mouse properities" It only changes sensitivity for RIGHT and DOWN move, but LEFT and UP stay same as Windows default.
I tryed changing mouse settings, mouse drivers, reinstalling windows, inserting mouse to external USB ports with noeffect.
I suspecting it`s problem with my new MB ASUS RAMPAGE II extreme
Have 2mices( razor copperhead, logitech g5).
Windows xp64 SP2
Had the same problem with my copperhead mouse and the only way that I was able to resolve the problem was to flash new firmware into the mouse and install the newest copperhead drivers......
