I believe the Chrome issue is a conflict with Chrome's popup blocker or same-source policy. I created a page with nothing but a textarea and put it on the same host where the request with your text goes. It works there in Chrome. I then put the same page on another host and I get the "no writing errors found" response. If it's a security policy or popup blocker, that may explain why I'm not seeing any errors from the browser. It looks like I'm not going to be able to fix this for Chrome without some serious work arounds.
