Folks, it appears that widgets can be tied directly to specific themes. There must be a PLIST somewhere that lists the theme names that can be used with any given widget. I think they do this so that the widgets can be styled appropriately for the theme in which you place it.

Anyway, if you try to add an AdSense widget to any of my themes, I believe it will crash iWeb. At least that’s what it’s doing to me. Until I figure out a solution for that, just create a page in your site using an Apple theme, add the AdSense widget to the page and then copy and paste it into the page where you really want it. That will work.
