Can't zoom in with the editor

[Mepper]

Hey! So I guess this is more of a tech question, but for some reason in the editor I can zoom out with Mouse wheel down, but Mouse wheel up zooms out too. I checked the "Configure Controls" menu, and everything is set to default (MsWheelUp = Zoom in, MsWheelDown = ZoomOut)

Anyone else having this problem?

EDIT: After lurking the Beta forums, some guy that had the same problem figured out that I had it's a glitch that happens to most Microsoft mice. I just had to download some "IntelliPoint" program to fix it.
