I have a mc with a setInterval that calls a function repeatedly to load external jpgs
The mc in question is a little movie in a bigger movie, and plays only when you click button A.
Problem: When the mc is playing, you click button B to play a different mc in it’s place. However, the output window begins to throw up ‘path not found’ errors - so the setInterval is still active, even though the mc is no longer visible
Do I need to clear setInterval when I click button B?

Thanks Sen!
I’m away from my PC that’s why I’m asking (instead of just trying it)
I’ll give it a go when I get home
:sure:
