Flash8 :: Insert An Swf File Into Another Flash File?

I'm trying to insert an SWF flash file (a game) into another Flash file. However, when I import the swf file into the library and drag it onto the frame (and insert the stop(); command onto the frame action to stop it playing the whole movie), the SWF file plays constantly, ignoring all the actionscript and button commands in the game SWF file.When I try inserting it using the Window component, the game SWF refuses to play at all - it just stops (clicking buttons in the game work, but it goes-to-and-stops instead of go-to-and-play like it's supposed to do).When the game SWF is played by itself (by just double-clicking to open it from Windows Explorer or embedding it in a web page), it works fine.
