Each time you type text, it should be its own layer. If not, click the new layer icon in the properties box at the bottom right of the layers tool pallet. This should manually make it a new layer.
I do this completely different so I can't really diagnose the issue you are having.
Im gonna take a guess and say this for you.
In the tool pallet, make a box selection, then insert your button there.
Then maually type in what you want. Then select both the button and the text and group them.
Then do the same for the rest of the buttons.
or
In your document, Make the button there. Don't type the text on the button but out to the side. Do this for each button. Then move them over on top of the button.
Maybe since you have pasted the button over and over, Its treating the text the same way.???
If this web site is all done in tables then the nav will be named what ever the page is you want.
So if you are using the same nav for all pages, the export it each time naming it the pages that coinside with each catagory of the nav bar.
Home.htm
Contac.htm
about us.htm
Get it ?
Or export it as index.htm, onec and open it in dreamweaver, make the modifications there, and save that new page as, whatever.htm -example.
Hope this helps.
Its much easier to create it in photoshop and then open it up in fireworks and then slice it up.
I guessing you just need the buttons. So maybe try and export just the buttons as new gifs, and import them into your new html document in dreamweaver.
Thats all I can think of right now. Its not to hard when you get the hang of it.
I'll check back tomorrow. Its late at night where I am.
