Mouse look left / right move slower then up / down?

[VincentVolaju]

Am I the only one that has this problem? It seems like its only in EQ that my mouse look speed where scrolling left / right moves MUCH slower then when looking up / down. Its so bad that I have to keyboard turn with A and D in order to look around.

I know its not my mouse itself cause its works fine in everything else I play, and if I up the sensitivity on it it will make it a little faster, but then my scrolling up / down is like INSANE fast.

Anyone else have this problem / know a fix?
