Make the mouse pointer disappear?

[EZ1]

I like having the mouse pointer visible. I leave it near the speed and alt guages so when I look in that direction (with TrackIR) I get the readings without having to interpret the old guage indicators. This really helps when flying a lot of different planes and you need that info quickly.

I place my mouse in the center, then when I turn my head with track ir, I use it to read the gage's labels for the engine info and heading.
