The IGHtmlEditor does not work properly when you place it inside a jQuery-ui dialog, running on Firefox. It seems to work fine in IE and Chrome.

All you need is some HTML:

    <div id="dialog" style="display: none;">
            @(Html.Infragistics().HtmlEditor().ID("igHtmlEditor").Render())
    </div>

Then some JavaScript.

$("#dialog").dialog({ width: 600, height: 600, modal: true, autoOpen: false });

$("#dialog").dialog("open");

This is causing us a huge headache.

As for what's wrong, pretty much all the functionality is broken (try using the toolbar). It's also got rendering problems. We're using Firefox 22.0

Thanks.
