Guis...
 

Ok, my gui image was screwed up thanks to a certain server who edited the default gui window image. -.-
So, how can I get it back to normal? =/
Cause right now, I cant see the background, or the close, minimize, etc buttons....
So, its basicaly blank...except for all other guis inside it, buttons, scroll windows, text, etc.
I redownloaded the graal images pack, but it didnt help...
This has happened 2 times before, and I had to reinstall graal. x.x
Is there any way I can fix it without reinstalling graal? x.X

same here, but I don't think there is a way without reinstalling it.

right click the image -> properties -> read-only

First delete FILENAMECACHE.txt to make sure Graal sees all files (it is doing a full scan then again). If that doesn't help, then delete all files starting with gui. Normally Graal is downloading graphics again when they are missing.
