i ve a really boring problem with 3DS Max.

everytime i click and drag a spinner (specially the ones at the bottom of the UI) once the mouse goes outside the screen the spinner makes a very big gap.

Let's say i ve a vraysun at 2500m. I want to drag it down approximately somewhere between 1800-2200m, so i click and drag and once the pointer goes out of the monitor (easy if you have the spinner at the bottom) the spinner goes to -7000m

i never had this problem before...

can you help me ?
