I'm using an old texture pack from
Santa UI Textures for my actionbars.
Problem is they keep reseting to default when I open spellbook or move spells/macros. I saw some people commenting on the same problem on various forums but with no answers.

Afaik its the UI-Quickslot.blp controlling the actionbar borders. But maybe I am missing another texture file. I'm not sure.
Anyone know what could cause this or a possible fix?
