FWIW, I sill have the problem of not being to update a post after I edit it. Happens with Chrome and it happens with IE 10 though I use IE10 most of the time.
Make a post.
Read it over and spot a typo or wish to add something
hit edit and make the changes
Hit save - nothing happens
Hit save again - nothing happens
No little spinning wheel or circling arrows - nothing.
I copy the post, hit refresh on the browser, see the old post.
hit edit again.
Delete all the text
Past in the new post
save - and it works 95% of the time.
Quite an annoying process. I hope I am the only one having this problem.
IE10, Win 7, cable connected
