Not exactly news: Chrome crashes frequently when editing math in MSE. And the crash often loses all the work (change the last
always, if we are editing an already posted answer).
More than a year has passed (this post, from April 2012, mentions that the problem started about 6 months before), several Chrome versions have passed (17 to 23), the issue has been reported several times (thread above, and several others), but, in my experience, things are exactly the same. It happens, in my experience, regardless of computer, Chrome, or Windows version.
The only different behaviour I've experienced lately is that, instead of the old dreaded "Aw Snap" message, the Chrome tab freezes completely (nor even a copy is possible).
Apparently, nobody has a clue about the causes (I'm aware that the whole thing is technically quite complex) and we are just hoping that some update (Chrome, MathJax, whatever) will soon fix things. I, for me, am losing those hopes. Don't take this as a rant. I love SE. It's just that, perhaps because I edit frequently, this is extremely frustrating for me. Beside raising awareness about the issue, in case it helps, and besides asking if there is some current work focused on this problem, I'd like to know how the other users (specially the most active people, who type much more than me) cope with this. Have you all ditched Chrome, at least for MSE? Do you disable the automatic math rendering?
I also wonder if, for the benefit of new users who are not aware, this issue should be more visible (eg, in the help for the editing).
Update: I'd also like to know if someone has found some reproducible scenario of the crash (I doubt it), and if there are some relevant opened issues at Chrome or MathJax. On Chrome, I don't see much.
