[Closed] the LAG

Max viewport wierdness never ceased to tease me.
Often when I use script controllers or scripts with change handlers ( eg. on spinner change),
there is that lag with some strange continuation.
I click and drag and the object is crawling slowly like a ball on a thread in the water.
With spinners there is yet another thing…when I drag they firstly go very slowly just to ride to infinity in an eye blink later.

I don’t think it’s caused by computation time because it happens in very easy things and quite often.
