Am I misunderstanding the use of the activate method in this snippet? Or does this script demonstrate a problem:

myStart = (new Date()).getSeconds();

while (true) {
 if (app.visible) {
  myCurTime = (new Date()).getSeconds();
  myPeriod = myCurTime - myStart;
  (myPeriod < 0) ? myPeriod = myPeriod + 60 : myPeriod;
  if (myPeriod > 10) {
   alert ('You have failed to hide the application in ten seconds');
   exit();
  }
 } else {
  app.activate();
  alert ('Application was invisible');
  exit ();
 }
}

I get a run time error when the app.application() command is reached (happens if you Command-Option-Click on the Finder after launching the script). This under Mac OS X 10.3.2.
