Transitions and non-Transitions?

I’ve been using transitions between externally loaded movies with this code:

on (release) {
if (_root.currMovie == undefined) {
_root.currMovie = “movie”;
container.loadMovie(“movie.swf”);
} else if (_root.currMovie != “movie”) {
if (container._currentframe >= container.midframe) {
_root.currMovie = “movie”;
container.play();
}
}
}

which works great.
But when you need to load a movie without a transition what code should you use?
I tried:

on (release) {
_root.container.loadMovie(“intro.swf”);
}

which worked but after it loads none of the other buttons work anymore, has anyone had this problem, if so what would the code be? I have tried all kinds of stuff to no avail.
