Mouse Listener and key listener problem

Hi;

I used key listeners to detect the block in my crossword application but I have a focusing problem going on. I’ve tried everything but still couldn’t find a solution. By the way I used a code that uses mouse listener to highlight the area I want to use but it sometimes craches the flash player. My .fla file is included in the message. Please help before I go mad. :angry:

Thanks…
