Flickering/Unsteady Edges

[Azhubham]

Thanks Urrah, but I had allready read your thread about en/disabling the crosshair :) - wich, sadly, nobody bothered to answer (including myself).

Up to now I played with standard-settings - so I think the crosshair is enabled - as long as that white dot in the center of my screen is supposed to be a 'crosshair' ;)
- or is there something else to turn on/off?

My cursor will turn into a movement indicating hand if I happen to place it over a door/object.
I could try turning it on/off later. - going to update my post, if anything occurs.
