Dave, I think that your problem is that externally linked casts are still loaded at launch of the movie. Therefore, the Windows side is still loading the cast with the QT members before you can swap for the cast with the mpg's. Try having an empty cast as your linked cast, and on start-up, determine the platform, and swap the cast accordingly. Of couse, this will cause a challenge in that you will need to bring the movies on screen with lingo, because there will be no "hard" links to them...

I'm making a cross platform program that utilizes MPGs and has completely separate casts for each platform (DirectXtra cast for the Windows side and Quicktime cast for the Mac side). Even though I'm dynamically linking the cast after determining the platform upon launch -- the program is now showing a Quicktime Initialization error on the Windows side. The program has a stub for each side and goes through an "intro" movie before it comes to the final program. It's at the final program that it shoots out the error. I'm certain there is no "Quicktime" cast member in the internal cast and there is no xtra reference to the QT Asset in the Protected Movie. (Not that is should matter since it isn't the stub, of course) Is there any way the original movie could still be looking for the QT Asset even if there isn't a single reference to it anywhere in the program? Thanks in advance, Dave [To remove yourself from this list, or to change to digest mode, go to http://www.penworks.com/LUJ/lingo-l.cgi To post messages to the list, email [EMAIL PROTECTED] (Problems, email [EMAIL PROTECTED]) Lingo-L is for learning and helping with programming Lingo.
