Internet Explorer being a complete bi*ch....

my stupid IE works ok on all my pc's but on one of them the stupid things gives me a ton of those script errors/debugger things when I try to check my yahoo or msn mail. I can check it however on the otehr pc's fine. Is there any way to get rid of these annoying popup error windows or disable them?

tools->internet options->advanced->check "disable script debugging"

thanks bro
