forms have "On Timer" or Form_Timer events (same thing), open up form properties, and set the "On Timer" event to "[Event Procedure]" and set the "Timer Interval" property to 1000 (milliseconds = 1 second) and then in code under the Form_Timer event add the code to check the IF statment and open the popup form. You may need to add a public boolean variable to disable or exit the timer event after it has been run once otherwise it will execute ever second. You can also change the Timer Inteval to 0 to disable the event.
