Two questions and a problem.

[refriedfood]

This is great, and I thank you for working on such a project--please continue.

First, I wanted to ask if anyone knew the CSS selector for the chat window text (when writing with someone) the small is too small and the default is too large, and I wanted to specify its size. I was unable to find the selector in the friends.original.css file.
Second, I wanted to know if there was a way to modify the message sound using a skin to only manage the message.wav?

The problem I'm having is simple, and I believe a possible bug. The only changes I have to my css at this time is the following, because it's the only thing that works:

 * {
   font-family: Arial !important;
}

Everything else makes my friends list and chat an unusable black screen or oversized icons that overlap, etc:
