This is now a catchall for different Drag & Drop issues.

Original issue
When moving the bar by drag & drop, the textboxes for horizontal and vertical (beneath their respective sliders) go blank when they should have the new X and Y coords. Sliders themselves are the correct value and the issue disappears on a /reloadui.

Multiple drag/drop not saving
Reported specifically for Hunters.

When you drag and drop once, you are unable to do a second drag and drop action. After reloading UI the position is reset.

Looks like the second part (multiple drag/drop) is due to inconsistent variable naming.
