Hi,
I came across the same problem today in a project. The "?" was just killed bi the DataLoader after i downloaded the latest greensock package. It's Windows, Firefox 3.6.11, Flash 10,0,32,18 Debug Version. Unfortunately i just have too little time to build an example, i hope i can do it later. I'd love to use your great LoaderMax, but for now i had to deactivate it not to worry my client.
But apart from that your library is really great!
