So I leveled up today to 15, and got a Raspberry Pi and a R.A.T. 7.
The mouse works perfectly in games, and really is a precision piece of tech (compared to my £10 wireless combo from Novatach), However when I move my mouse on the desktop it's really disappointing and crappy.
Basically, when I move the mouse to the left then the cursor moves to the left. However, moving it to the right makes it go right AND upwards, in a diagonal line, even though I'm carefully watching my hand movement and it's perfectly parallel to the edge of my desk! Repeating this movement yields the same results. Pretty much same on the vertical axis.
I'm using Windows XP 32 bit, and I know I ought to upgrade by now, but the problem seems to have something to do with how the OS manages the mouse, because as I said before it works perfectly on games, but as soon as I tab out into the desktop or use the default windows mouse it turns into an unusable stuffstorm.
Yes, I have all the latest drivers and also the software.
Any help would be appreciated.
