I tried it with two different browsers and I'm pretty sure its not a cache issue. I'll try deleting all of the files after I re-create the buttons and then re-publish.
I agree that somethings not quite right but I cant seem to put my finger on exactly what triggers the issue. I'll get back to you folks when I get home from work and I have time to play with it.
Adding navigation buttons to a page should have been a simple process requiring minutes not hours in VSD.
Thanks.
