Ashley,
It's not C3, it's Chrome.
I have the same issues with C3 in Chrome on 2 Windows laptops and a Chromebook.
(I even have issues with Google products in the Chrome browser)
The problems I have in C3 with Chrome are:
When I go to the editor's template/demo page, some of the demos don't show up.
Also, when I open an HTML game that I've made with C3 sometimes game features don't work, usually newly added features don't work, but sometimes even features that had been working are an issue.
Typically clearing the cache will clear up the issue, but sometimes clearing the cache and a reboot is required. I disabled all the browser extensions and even removed them at one point, with no change.
And again, when I'm having these issues, everything works just ducky in Firefox and Opera. And it's not only C3. I have similar issues with websites that I've built. I think I'll be moving back to Firefox while Chrome figures out its issues.
