[FlashCS3-AS2.0] Drawing Board problems and issues.... Help!

ACTIONSCRIPT 2.0:

I have put a drawing board on my application, but i cannot figure
out how to get a colour selector…? Any ideas on this?

Another problem with this, is that when the page is selected i can draw
out of the board, and also when i navigate to another page i can
continue to draw on other pages (not good!)…

Heres the script:

**this.createEmptyMovieClip(“drawing_mc”,this.getNextHighestDepth());

this.onMouseDown = function() {
drawing_mc.lineStyle(10,0x000000);
drawing_mc.moveTo(_xmouse,_ymouse);

onMouseMove = function() {
drawing_mc.lineTo(_xmouse,_ymouse);
}
}

this.onMouseUp = function() {
onMouseMove = noLine;
}**
