Guys, I found an error (at least in my install) where after editing a comment I got an "underfined" error.

I traced down the error to client.js script, near line 280. It appear that at least for IE7, the responseText attribute gets undefined when removing a post, so I added a previous check for it before testing its value.

Here's the fix

if (JOSC_ajaxReady()) { // @willy - fixed on cases were responseText is undefined (perhaps a more deep fix avoids this...

                    if ((JOSC_http.responseText) && (JOSC_http.responseText != ''))

						alert(JOSC_http.responseText);

                    else

						JOSC_removePost(document.getElementById('post' + id));

                }

Perhaps a better fix is possible or even it's just my particular installation.

Hope this helps, Willie.
