found my problem. At some point in an earlier exercise I had set the ViewStateMode to disabled for my default page; doh. I haven't worked out why this causes the behaviour I saw (ie why would disabling viewstate mean I could switch from monochrome to darkgrey, but not back again - why does the ThemeList_SelectedIndexChanged() function only get called the first time. ), but I'll mull that over...
