I know this isn't the place but I found this 2 days after you posted from trying to go through the wowinterface forum, after you basically necro'ed the 4 year old thread, so thanks for posting a solution even if it was late, it's usually helping someone in the end :D

Exactly :) I knew that if I ended up there. Others will too, even if its old thread.
I'm happy that I could help. enjoy ^^
