Hey Joe,
I'll fix that so it uses the skin setting.
I do want to clarify though, in my commit comments when I committed the change for this to the repository, I did say "make CKeditor work in UpdatePanel", but I have not actually tested that. At the time I had it in my mind that the HtmlSetting.ascx used an updatepanel and I did change the way the script for CKeditor is added to use ScriptManager which in theory might mean it will work in UpdatePanel, so that made me make that comment. But afterwards I realized that HtmlSetting.ascx is not using any UpdatePanel. So the change I made "might" have fixed it so CEditor can work in UpdatePanel but I haven't tested it to find out if it really works yet.
Best,
Joe
