No, its not impossible to do. I included lots of my wife's website at www.faraspence.com and it works just fine.
Why not post the link to the page so that we can take a look?
who me? :)
I see you used a frameset, will rush and try that ;-)
Hope it works out for you. Just remember that CityDesk normal view does not support frames. I used my external editor for that one too.
