with a flash site ...a pre-loading stage is where all the scripts, images etc is actually loaded so when the page accesses all the data is "live" so to speak. what make the transitions smooth is the speed of the connectivity and the computers capability.

IOW, my flash site looks swell on a desktop but pull it up on my old laptop and it begins to get choppy...I do not think it's your wifes code, I believe it is the clients machine. Also is the client viewing of a staging server or has the site been uploaded to the clients hosting server, this also affects the indexing speed...

I hope this makes sense
