Macromedia Director Projector on Leopard, Mac osx 10.5 doesn't runns

["Cybrx" <webforumsuser@xxxxxxxxxxxxxx>]

Mac Leopard doesn't recognize a projector start file. It just shows up the unix 
file icon for a unidendified programm ex. like it shows an win exe file or the 
ini file. 
 "cannot execute binary file" comes on the log file
 The interesting thing is on an older g4 mac it runs correct, but for example a 
new mac g5 it doesn't.
 Somebody got any idea how to solve the problem?
 Thanks for info.
 Cheers
