Ah ok. I don't use Chrome so I've never come across the problem. I try to keep the site compatible with Firefox 3+ and IE 7+.
I've found the problem:
Standard view won't load in Chrome - tries to download 'gz' files - Gmail Help
Since Gmail relies heavily on AJAX and this site does, too (the chat bar, recent topics, quick reply and more), I'd say it's something wrong with Chrome. Try updating if available
