If you wish to use any of the meta-characters (#;&,.+*~':"!^$[]()=>|/@ ) as a literal part of a name, you must escape the character with two backslashes: \\\\. For example, if you have an an element with id="foo.bar", you can use the selector $("#foo\\\\.bar").

Ahh, I see the problem. This doesn't work in 1.4.2!
