page needs refreshing for game to work properly

Hi all :) Im new so please forgive my ignorance.

Ive uploaded my game :)

arcade link

thanks SCIRRA for the software, thanks people on forum who answered my questions.)

The game loads fine now, but I notice when I play it on a "new" device I need to refresh the screen to get it to run properly. Is this normal, or should I be using a pre-loader or similar for the game ?

Once Ive refreshed the screen the game runs as it should.

Thanks again,
