Sometimes a LUA error can occur when attempting to move the Script Editor window:

I get this every time I try to move or resize the window. The whole window becomes unusable until I open it again.
So that i am currently experiencing this, and thought I'd try to see what i can learn.
- First, it's the main window (
GetModule('UI.MainPanel').MainPanel) which inherits theBasicPanelclass. - Second, it's not LibWindow library, as calling the
SavePositionmethod works as normal.
I've tracked it down to the StartMoving/StartSizing methods that cause the issue. In the OnDragStart script. they're called, and for some reason, remove all the frame's point. That instantly triggers the OnDragStop script, calling LibWindow:SavePosition() which tries to access the frame offset via :GetLeft() and that causes the error, as the frame has no points.
What i can't figure out, when calling StartMoving on the frame outside of the script, the frame loses its points (and for me other elements disappear)
This could very well be a Blizzard UI issue, or some other problem causing StartMoving to do this.
