Hi kylek,
I've not updated the forums on this site yet to 3.7 beta 2 or 3, its running 3.6.8 (stable). We have 3.7 beta 2 running on a test board, and its not got any issues, I just checked the
arcade installed on the test 'bed' and its all working fine. What you're describing sounds like an issue with the style, perhaps a template edit done incorrectly...???
