When I'm editing pages, the main editing area with the tabs/tinyMCE editor is way off to the right.. so far that I can't even access it. It leaves behind just a big grey space. Works in Safari.
I tried to test demo.silverstripe.com, but it seems to not be working at the moment. Due to a couple of javascript errors, it seems it won't redirect me to the CMS after logging in.
Is this a known bug?
