I'm currently going through a tutorial on building a contact form. When I try to type anything, my property panel is empty. This mean that if I want to change anything, like the font, size etc. I have to do it in the top menu.
I've tried quitting Fireworks, then reopening it with a fresh new document -- same thing.
Use the symbol properties panel, not the regular properties panel and change the label of the selected form symbol in that panel. HTH
