Themeroller (jQuery UI 1.8) - 2010-03-22 not working?

Howdy; it appears that the themeroller is not actually adding the customizations to the output file when I attempt to download a theme I've rolled.  
1. Customize theme
2. Select "Download Theme" button
3. Customize JQuery UI download

[ all this is with 1.8 ]

I've tried both specifying and not specifying the custom theme name, and it appears that output is generated both under ./css/[theme name] and ./development-bundle/themes/[theme name], but nowhere in the generated CSS do I see my customizations.

Thanks!
