Spell Effects Window Problem

[nirrub]

Hi

New to this UI but implementing it with a vengeance
The Spell Effects window (that shows all the active spells on me) is right on top of my hotbar. I tried moving it around but I couldn't figure how - I use the right button menu to unlock it, moved the cursor till it showed a multi-directional arrow, but when I press left mouse button and try to drag, all it does is move the camera around.

Anyone got any thoughts how to solve this?

Thanks.
