I'm a new (very new!) Flash developer, and I'm trying to find out what versions of the Flash plugin originally shipped with various versions of Internet Explorer. I have a customer who is willing to go along with a compatibility "baseline" of Win95 OSR/2.5 (which came with IE4), but I'm not sure if that has Flash 3 or Flash 4.

I'd also like to read up on the differences between the versions, if someone could point me in the right direction for my research.

Thanks, and I love the site!
