@platinum Did you get this resolved in the meantime?
... sorry I just stumbled across this thread.
As for disabling JS, that works indeed, but I'm afraid it will break a few things. Quick reply might not work, ads will fail, rating will be impossible, the scroll-to-top won't work, my site usage statistics will fail and probably a few more bits which I can't think of right now.
I'm curious if more people find the sticky menubar annoying?
