Tried but failed...
 

I downloaded a skin which only replaced the .dds files of profit, and the background to my group and raid windows now starts out black at the top and clear at the bottom, this drives me nuts when raid healing, I've tried replacing a bunch of the files with the originals but no fix yet.

Can someone please point out the file name that has the background for this?

Found it... windowelements.dds

I put this in photoshop but cant tell even against a white background how or which part of the pic fades from top to bottom, any ideas?
