Setting new style as default

[beka]

I went to Admin CP -> Styles Templates -> Style Manager ... Then for every style except the one I want people to see ( I only want them to see a Xmas one), I went Edit Settings -> Allow user selection? -> No The only one I left as Yes, is the Xmas I want people to see.

But all that has happened is the default style is the only one that comes up now when people log on, and the 'Quick Style Chooser' drop down box in the left bottom corner has disappeared.

What am I doing wrong?
