Chrome is becoming a pain in the arse!
Some of the C3 demos on the editor's demo page, don't show up. Other show up, but won't load, but only in Chrome. They show up in FireFox just fine. There is a terrible lag from time to time, but only in the chrome browser.
Chrome holds a lot in cache, sometimes if I clear the cache everything clears up, but then of course, I need to login to everything again.
However, FF loads and runs sooo slow, I can't take it. So I keep using Chrome.
I know that doesn't help, but at least you know you're not alone.
