Crystal FTP's download meter.
 

Here's a weird one: I can't reproduce it but I've seen it a few times now. When 1.6d118 loses focus and Crystal FTP gaines it, I find Crystal's download progress dialog box has popped up. I close it, switch back to LimeWire, switch again back to Crystal and another progress meter dialog box pops up. Yes, Crystal is open but not connected to any FTP server.
