Thanks for all your help Aran.
I am testing with shared objects now, and now i know that they will work
without a full flash site, i will most likely go that way instead.
I am primarily a .NET developer but have teamed up with graphic
designers that do some cool stuff in flash but don't know how to code.
So I get the ActionScript jobs.
We are about to embark on a full blown Flash based CMS for flash sites
using .NET data layer.
See how many hairs I lose over that one :P
Kind regards and thanks again.
Maurice.
