MathJax rendering freezes post editor
I've found that while typing a post, whenever the MathJax renderer runs the editor freezes and I become unable to type anything in it. This is quite annoying, as it happens quite often - I can only type a few words before the MathJax renderer runs and stops me. Even just moving the caret with arrow keys will cause the renderer to re-run, making it extra annoying when I move back to fix a typo or something.

The rendering happens when auto-save runs. We weren't able to solve the problem directly (something something Javascript is single-threaded something), but there is now a preference to disable auto-saving, which is a work-around. Go to your user profile and then to the "preferences" tab.
Be sure to save your post yourself when working on something long or complex with auto-save turned off. You can use the new "save" control in the toolbar to manually save a draft:
