I can't see the theme of the page in desgin mode

[Javier Martínez]

Hi
I'm using themes in my aspnet web site, I set the thema in the web config.

In runtime all works fine, I can see the page with my theme but in the
design mode of the page in VStudio 2005 I can't see the theme.

What am I doing worng?

Thanks in advance
Javier
