[regex-coach] problem with dot '.' inside brackets

I've been using Regex-Coach 0.8.4 on Windows to test some SpamAssassin rules and noticed something odd: Placing the following expression: [.|m] to match the following data: bleh.com Matches the '.' in bleh.com and not the first non-linefeed character as the '.' character in the expression should match. It's almost as if I had excaped the '.' like '\.'. Using the expression '[.]' yields the same result. I've also noticed that the non-match character '^' doesn't work inside brackets as well. Is this an error or am I crazy? Bryn
