I'm not familiar with this issue. When you guys experience glitches, will you please email me or use the feedback tab? Let me know what browser & operating system you're using, what page it happened on, and anything else you can think of that might be relevant. Screenshots are always good, too.
There are so many possibilities that, even if I'm on the site at the exact same time as you, and even on the same page, I might not have the same problem- especially if it's a browser thing, so please keep me in the loop with emails and feedback.
I'll look into it. It's hard for us to support the non-standard browsers because the ones that most people use (Chrome, FF, IE, Safari) keep us hopping as it is- their updates require updates here too, but in looking online, those two are open source versions of FF and Chrome, so one would think they'd function much the same. I'll try downloading one or both of them tomorrow and see if I can get it to give me the same issues. Maybe there's a simple fix.
