Thanks @Derek3803, but I still can't. Have both layers in the same order as on the screen example. I can select it, select the color and line tool but can't draw. It's probably something dumb that I just don't know. Had a step drive me crazy cause it was missing the instruction to select the .fla before trying "Insert>" since it only appears when the .fla is selected.
I cannot get this to let me draw the white line.
I draw it and as soon as I let go of the mouse button it disappears. Any suggestions?
I am doing this with Flash CS3 which I found at the following link, with a 30 day trial period.
