Good that it's working now :) One thing came in my mind which could have affected, if you had very old installation of OWB and fullscreen fix script, the allowed sites list for fullscreen fix script might have been outdated. I noticed once that newer scripts added more urls to that list than older ones. And in that case you should have removed the script completely and not just updating its file, before adding it again as newer one.
