I'd prefer to see pictures
This is a good tutorial, where you've explained everything you need concisely and correctly. What I think you need to give us is a few diagrams or screenshots of the program, to show us exactly what you are getting at with the directions.
Then we come to the directions. They are concise, as I've already mentioned. The problem is that the font is a little difficult to read and we could do with putting more breaks in the text, as it strains the eyes. This may be countered by the fact that when people are actually using it, they may only use it for reference as they are making the preloader. This is probably the intention of the flash, but certainly making either the text bigger or chaning the font would be beneficial.
