Okay, here's what you can do to get the window to change colors when a new notice arrives and the @Notice window isn't active:

Code:
ON ^*:NOTICE:*:*: {  
  $iif(!$window($+(@Notices-,$network)),window -ael $+(@Notices-,$network) Arial 12)
  aline $+(@Notices-,$network) 4( $+ $nick $+ ): $1- 
  window -g1 $+(@Notices-,$network)
  beep
  halt 
}


Notice the 'wingow -g1' line. Sorry I keep posting, but I think that every change that is made is vital to what people may want done.
