Movie clip dissapearance (as2)

http://www.carlsonmedia.tv/new/3.html

I’ve got a scrolling movie clip on that page.

I have 2 problems, 1, when the last button in the scroll is clicked, the movie clip snaps back to the first view and doesn’t remain where the scroll is like the rest of the buttons.

here’s the code for the scrolling:

stop();
panel.onRollOver = panelOver;
function panelOver() {
this.onEnterFrame = scrollPanel;
delete this.onRollOver;
}
var b = stroke.getBounds(_root);
function scrollPanel() {
if(_xmouse<b.xMin || _xmouse>b.xMax || _ymouse<b.yMin || _ymouse>b.yMax) {
this.onRollOver = panelOver;
delete this.onEnterFrame;
}
if (panel._x >= -5.5) {
panel._x = -5.5;
}
if (panel._x <= -560.5) {
panel._x = -560.5;
}
var xdist = _xmouse - 210;
panel._x += xdist / -7;
}

the other problem is that if I go to a different window for a while, and return to that window, the movie clip has dissapeared, and I have to refresh to bring it back up. Any idea why that’s happening or how to combat it?

Also, enjoy the text on the side of that page, I love non-sequitors in my mock up pages :p:
