I exported a small prototype from Fireworks CS5 to HTML & Images & tested my hotspots in my Firefox browser. That worked fine.
Then in Device Central CS5 I did File > Open File & selected the home page for this protototype. None of the hotspots worked in Device Central.
Any clues? Shouldn't they work in Device Central?
Please forgive me. This is working. I didn't notice because the page changed so smoothly & I couldn't see the part of the page that indicated it changed. Yeah it works!
