When you clicked the link Old_Default.. Post there your issue your having trouble with on his UI.. Ill pass the word. Are you unclicking .." keep your layout " when you load the UI? I'm not exactly sure what you mean
I tried to upload the Default_Old SpellBookWnd.. well the file exists already :P .. So you will have to find it somehow.. I did not see where it says Old_Default .. or Default_Old spell book window on any title..
