Just started using this wonderful app. In a couple of weeks I've sussed out how everything works, and built my own interface and maps for tours.
I'm keeping my panos to between 1 and 2mb and they seem to work pretty smoothly in a window or full screen. Had a few issues with hotspots, but got there in the end thanks to a few posts on these forums, so thanks to you guys and gals that contribute your answers here.
I've just put a load of panos up on my site at http://www.ambientlight.co.uk
Thanks again for making it simple to produce quality flash panos!
