Why won't text appear?

I have never heard of this problem but it has now happenned to me twice. I have text, some copied from Illustrator, some typed right into Flash, all static, all sitting in a movie clip. The text appears just fine on the fla AND on the swf. But when that swf is loaded onto another swf (the main page, and through the use of an xml menu) then the text just disappears. I am loading many swfs onto the main page and haven’t had the problem. But the most recent two swfs I created have swallowed the text into a black hole.

Can anyone tell me what is going on? I tried asking this once before but got no response . . . :-\

Thanks.
