Using RadTabbedWindow I noticed difficulty dragging maximized windows between monitors. It seems to happen in multi-monitor environments and only when dragging Left of the PrimaryScreen.
In the video I've included , the blue window is a standard window and can be maximized in one drag across any display.
The white window is RadTabbedWindow and the drag will default to the PrimaryScreen when dragged to the left-most display.
Any help would be appreciated. Thanks
