Well Hi Grant. My FontLoader will always download fonts which will be available through the whole application. Even loaded swf's will be able to use these fonts.
But at one point, my "host"-file might load 3 fonts. And then when "myChild.swf" loads in, it might require an additional font which should be loaded. I need eventlisteners so that I at least can know when the fonts are downloaded. And oftenly this function that will be called is containing a another function call or a gotoAndStop or similar.. So the problem is I use the Singleton. If I got the FontLoader.getInstance() in the "host.swf" and one in the "myChild.swf" they are both having listeners setup for the fontloader-instance, they will both get executed when "myChild.swf" is calling methods of the FontLoader-instance. One way is to remove the event-listeners in "host.swf" when it is done loaded. Then they wont interfere with the "myChild.swf" when it is loading any additional font. I could send you the files with the problem, it might be more obvious what the issues are.

I need to know that to help you revise the design..
