If you use the stop command and the movie stops, why do movie clips still animate and buttons still work?
A1:
The stop command affects only the flow of the main timeline. Symbols on the screen, such as movie clips and buttons, still move and respond at a normal rate.
Q2:
The nextFrame command goes to the next frame and then stops there. What if I want to go to the next frame and then have the movie continue at its normal animation pace?
A2:
You can use the nextFrame command to go to the next frame and then immediately follow it with a play command.
Q3:
Can I place functions inside button scripts?
A3:
No. Functions can be placed only in the main timeline. You can only put on handlers in button scripts.
Q4:
Can I place buttons on a frame but make them inactive?
A4:
Not as easily as you think. You can place a button on a separate key frame and then just not attach a script to it. The button won't do anything, but it will still look active. A better method would be to create a graphic symbol that looks like an inactive version of the button and place it in the same spot where the button would normally appear.
