Hi Mike:
Davdesign will surely come up with an answer on your preloader... Meanwhile here are my comments:
1- I think your preloader is working... it's not just showing the picture the first time around, but on a second visit(the picture or movie being in my machine's cache) it shows up quite fast. Hiting the home button then causes a problem since you're not unloading that picture's movie, and it covers the menu.
2- You don't seem to have solved your email form problems... Guess you have these more important problems to solve.
3- As for cutting down the size, I think you should make several movies with each item, and only load them at user's request(ie when he hits one particular item). Work on a copy of your fla... In case it doesn't turn out the way you want it to. In anycase, your loading time is not that bad... On my 56k standard connection, I can easily suffer it because you're offering me something to look at rather then just an empty screen. Maybe it's also because I like hostas... Mine are buried under 2 feet of snow right now... but spring is coming soon!
Regards,
François Gill ;-)
