@Uhrwerk: I tried it before but it doesn't really change anything. Seems like it's output related.

@Ch40zzC0d3r: I just gave it a shot and it's working (kind of). Thanks for the info.. I actually expected it to be trickier than that

The only annoying thing is that I have to set the cursor each frame again. I don't think it's supposed to be like that, probably a contradiction with acknex resetting the mouse pointer.
Also using a custom cursor file for some reason doesn't work. Not sure if the file isn't being found or if something else is the problem, but I guess I can figure that out myself.

but thanks again guys
