2 Problems with LC Bot

Hi guys,
Sorry but I don't speak german, but can someone help me?
I'm using this bot: [Only registered and activated users can see links. Click Here To Register...]
He is working very good, but sometimes I have 2 problems:

1- Sometimes my character keeps atacking a unreachable monster (monsters that "borns" inside the walls) . Theres any form to stop this?

2- Sometimes my character runs out of the area that I would like him to stay. Theres any form to keep he at a specific area?

And is this bot that I'm using the best? Or have some news?

Thank you =)

1 & 2 : No (I think so)

Well for the problem number 1, I've created a stupid AHK. That uses the TAB key every five minutes, so if my character is atacking a unreachable target he changes, as the same time he changes the target if he's atacking a normal one.
