This is a little updated version of the mIRC highlighter ^Alexis^ made.
original script: http://www.hawkee.com/snippet/5732/
I just found it annoying when bots were repeating my name coz i would get those messages over and over again. This triggers once and then waits 60 seconds before listening again. It also creates a balloon if mirc isn't active.

on *:text:*:#: { 
  if ($me isin $1-) && ($chan != $active) && ($+(%,$chan,.highlight) !> 2) { 
    echo -at 6[14 $network 6] 6 $nick   15has highlighted you in 6 $chan :15 $1- 
    inc -u60 $+(%,$chan,.highlight)
    if ( $false == $appactive ) noop $tip(You were highlighted,You were highlighted,You were highlighted in IRC network $network - channel $chan - by $nick - Message: $1-,20)
  }
}
on *:action:*:#: {
  if ($me isin $1-) && ($chan != $active) && ($+(%,$chan,.highlight) !> 2) {
    echo -at 6[14 $network 6]6 $nick 15has highlighted you in6 $chan :15 $1- 
    inc -u60 $+(%,$chan,.highlight)
    if ( $false == $appactive ) noop $tip(You were highlighted,You were highlighted,You were highlighted in IRC network $network - channel $chan - by $nick - Message: $1-,20)
  }
