Scratch

I just made a new project, which technically is a 1-player mini version of the popular Wheel of Fortune game.

It works fine in the Scratch player, but when I put it online into Flash, it does not work correctly and is unplayable.

Here is the link: http://scratch.mit.edu/projects/Inktail/2375721

When the project starts up, there are white blocks on the second and third rows that appear across the screen that should not be there, and sometimes no white blocks come up whatsoever. In the Scratch player, this does not happen. Also, the same thing seems to happen when I put it into Turbo Mode.

If anyone can help me with this problem, that would be great.
