Just for the record, I have not had any similar issues on my Mac using Safari.
Since the software for the site never changes, it doesn't make a lot of sense that an update would be required. I can see an update removing some old code handling capability and breaking a browser's ability to use WWGHA, but I can't see an update being required.
That is the non-tech me speaking. I don't know what I'm talking about but I'm bored until a theist starts posting.
Added: rereading the original post I see that you were talking about settings, so I misunderstood the problem slightly. You were clear. That seldom helps me
