I have a couple of issues of dragging a GUI panel:
As shown below, there is no issue to drag a rectangle panel with nothing on it.
If a textblock is added to the panel, the panel will jump when the pointer is down at the beginning of the drag.
If a rectangle in blue is attached to the larger panel, the panel will jump when the pointer is down in the blue area at the beginning of the drag.
Can someone help look into this and how to fix the issues?
