Macromedia is very close-lipped about the statistics on this. They'll brag about Flash being 'ubiquitious', or that 90% of websurfers can see Flash... but they get quiet if you ask what percentage can see Flash4. If you search the MM site you can eventually see these stats: It seems that around half the people don't have Flash4. I'm sure most of them have been to sites that 'suggested' that they install it.. but these people have declined. Flash3 comes installed with the 4.0 browsers. Netscape 4.7 and the newest release of MSIE have the Flash4 player. I dislike the way that Macromedia deceives people into exploring the shockwave.com website, after they've installed the Flash4 player plug-in. They make it appear as though it is part of the installation process. "Your player is installed when you see the animation above.. you may now click on the link to visit Shockwave.com" ...when you would prefer that the person return to your site, instead of getting lost in shockwave.com until their browser crashes and your site is forgotten. Because of that.. I went back to creating sites that I save as Flash3 sites. This way everyone can see them, without needing any plug-in, (unless they are real dinosaurs, with a 3.0 browser) FreeToys WelcomeSite BestDeelz You can still make pretty cool sites, even without the advanced actionscripting or MP3 compression of Flash4. Once the person has seen most of my site, I then begin incorporating elements of Flash4, as in this puzzle ... or the song that plays on 3dthrills
