Yeh, there's a lot of confusion about Flash and Shockwave, it took me a long time to work it out until I got Director! Macromedia get confused too, Flash exports it's files as Shockwaves but Director calls it's files shockwaves too. I might be wrong but to avoid confusion (sic) Macromedia calls files exported by Director as Shockwaves and those exported by Flash as Flash files even though they're called shockwaves, and even though they share a name, a slightly different plugin is needed to play them both. It doesn't really matter too much as Flash is mostly the format used on the web so it gets called shockwaves, but when 3D Shockwaves come in, (that's the .w3d format and created by Director 8.5) things might just get a little confusing!
