[flexcoders] Module question

[Wally Kolcz]

I have an app that loads modules as the user clicks buttons so they only 
get loaded when the user actually uses them... however I can see in the 
console says that each time the button is clicked, the module is 
reloaded.. resulting in many modules (or the same module being loaded 
and loaded). Is there a way to check to see if the model is already 
loaded and skip the reloading?
