Rotating in the xz and yz planes?

[Mentat]

Every time I rotate into or out of the screen, nearly everything goes haywire. But the same rotations in the XY plane goes fine.

Can somebody reillistrate rotations through the Z-axis?

And also, I normally have X and Y values in the hundreds, but Z values are around 1 and 2.

I fixed most of it. But my periphrial rotation still isn't very good.
