Due to compatibility problems on Internet Explorer after yesterday’s code update, I’ve temporarily disabled the Usability Initiative’s beta advanced toolbar. If you’ve had it enabled, you’ll just get the regular old edit toolbar until we re-enable it.
Hopefully we should have this resolved within a day or so, and it’ll be back on for all our happy testers!

RockMFR identified the source of the bug, I fixed it, Andrew pushed the fix live and iDangerMouse confirmed the issue as fixed. Thanks all!
