AS2: Help using the mouse for movement in isometric

I’ve been reading a bunch of the tutorials about using isometric in flash but they all seem to have one thing in common. They all use the arrow keys for movement. I’ve been trying to use the mouse for movement but have only met with frustration so far. I can get the movement to work but then the object collision on the tiles doesn’t work or vise versa. If anyone could help me out on this I would much appreciate it. Thanks.
