I power up and the last 3 out of say 5 or 6 times the screen is just blank, black. I hear the Apple C tone but nothing.

Another way to solve it is to use setTimeout and remove the controls after a short period 40 ms :. I found that I could also not use controls and instead just alter the display property after 40 ms:.
