Scratch

make the brick and the paddle a different color than the red bottom.

Okay, what you have is

Wait Until (Touching Color Red) And Not [(Touching a red brick) or (Touching a red paddle)]
Stop All

Which looks like it should work...and it does online.  But not always when it is downloaded (sometimes it does).  What I think is happening here is that it takes time for the computer to do the sensing on the colors and the touching of the sprites and in this case, the sensing on the color red is becoming true an instant BEFORE the sensing on the touching of the red brick is becoming true.  So the Wait condition is being satisfied and the program stops. 

The cure (as rockie suggested) is to change the color of the red brick and the red paddle to some other color.  I tried that and it worked fine.
