What do you think?
When building navigation panels in Flash, separate the buttons out from the panels or backgrounds. If you create a separate .swf that loads into the main navigation panel you can update the buttons across several variations of the same master panel.
I have just had a client with a different .swf on every page. All of them were navigation panels and used the same button set. It makes sense to keep updates to a minimum across several pages, speeding up the workflow. If a link or button style changes you only have to change it once – especially if you use instances to update the buttons themselves.other page
