I use the Chat plugin, but I found a bug when using it with the Twenty Eleven theme in WordPress 3.2. If you scroll, the chat window goes behind the header image.

I used this plugin with no problems up to WordPress 3.1.4, and it works find in 3.2 - except for this problem. I guess the z-index is the reason, but I am not sure about that.

Let me know the reason for negative vote? – Ramkumar Jul 7 '11 at 8:58
Please downgrade your version to WP 3.1.4 to solve this issue. Next to that you need to do a bug-report if you think it's a bug: codex.wordpress.org/Reporting_Bugs (I can't tell you why your question was downvoted, wasn't me) – hakre Jul 8 '11 at 14:41

It is indeed a z-index problem. The #branding element has a z-index of 2, in other themes (like Twenty Ten, the default in 3.0 and 3.1), it was not set.

A simple solution is to set the z-index of #chat-block-site to something higher.

    z-index: 10;
