I think I just found out why there are some people haveing a hard time with some themes and the message tab
It has some thing to do with the XML file. I to was haveing this problem and I grabed a clean XML file I have and placed it in the windows directory and wala..... it works again
Only one problem now I have to edit the XML to fix the weather location for the new icons again. I will post a clean XML and one with the weather edit.
