Exotherm - Quiet

I've been leaving Exotherm running (unregistered) on my computer recently. I noticed that I get an audible ding when a move occurs in one of its games. I suspect the FICS is including bell characters in move messages, which Windows plays when Exotherm prints the line to the terminal. I tweaked the script to strip bell characters out of received messages before printing them, so Exotherm is quiet now.
