Rotation settings in my reference pop-up panel are ok but units I can change Positions by sets themselves to 64.000 instead of 1.000. I can change it manually but when panel is opened again it is reset to 64.000. Any ideas how to fix this problem? All your help will be greatly appreciated!

Sorted it out myself. For some reason "Snap to Grid" was enabled

Right-click your reference window and select "Render Window Properties". Go to the Movement tab and change the values to whatever you're comfortable with. I suggest values that are powers of 2 (eg 2, 4, 8, 16, 32, 64, 128, etc).

Thanks!
