Problem with box2d flash game

Hi,

I am developing a flash game using box2d ver 2.1a and the game runs perfectly on my computer. But when i upload on FGL a yellow thin vertical line come after about 4000 pixels and then again after about 18000 pixels. Sometimes they don’t come at all. Can anyone tell me why this is happening?

Any help would be great… :slight_smile:

Thanks,
