Yes, I use this alias:
Code:
alias resetcolor {
  var %a 1,%v
  while ($window(*,%a)) {
    %v = $v1
    if ($window(%v).type == status) window -g0 "status window"
    elseif (%v == channel) {
      if ($chan(%v).idle > 600) window -g0 %v
    }
    inc %a
  }
}
called from a timer (with /scon) when mIRC start (on start):
Code:
.timertb -o 0 8 titlebar Ram (used/total) : $!ram $(|) scon -a resetcolor
Just ignore the stuff for displaying the RAM here (I left the timer call as it is just in case)
