In Windows the window jumps down for approx 30px (I assume it\'s gonna be the height of the drag&drop cursor) when grabbing the window and starting to move the mouse.
It is not the height of the cursor - it seems windows handles the position a bit buggy - when getting the position, it gives the correct top-left coordinate, but when setting it, it adds the decoration (that we're not showing).
Can you check whether it jumps for the same amount of pixels on multiple different windows systems (with different themes and caption-bar sizes) - if yes, we can introduce a small hack, if not, i haven't got a clue what can we do.

Tested it on 3 different windows systems and it was 16px but all screens resolutions were almost the same. I guess 16px will do the trick.
Can you check this now?
Made a clean build but still not working.
Can you check whether the same thing happens with the options window?
Yes exactly the same problem
Please try again
Works now!
