everyone who's ever run a loop or screwed up a while loop or an if loop knows that mirc freezes when looping.

Download a DLL called "whilefix.dll" from www.mircscripts.org and you won't ever freeze mirc during a loop again.

An example of using it in a script:
Code:
wait { 
  var %time $calc($ticks + $1)
  while (%time >= $ticks) { 
    dll WhileFix.dll WhileFix
    ;do what you want here
  }
  return
}
