No real panic... The update not going to cause that much harm, if the UI has a custom guild window then that will be kinda dead, but the rest will be trial an error,
Like a few things added here and few taken away etc....
Only thing on my UI version that messed up was the target window on the test server...
To be honest I never understood how the hell that worked with the parent window being out of line and 3rd of the size of the bars anyway LOL....
But after the update on the Test server it behaved how I expected it to ... EG: just showing what little was in the parent page lol.........But fixed that a few days back... Hmmm sorry mumbling on again.... Back to the point,
If you running the standard download of that UI then whatever windows break I am sure I can fix them for you if you get stuck oks
