Delphi Timers are not threaded. if you have two timers and put a sleep of 30 seconds in one, the time event for the other will not fire until the first is completed. They are run in the main application thread and are sequential.
One way you can counter this is if you have a loop in the first timer event, you can call application.processmessages which would allow the message to get through to the second timer. Threaded timers are a completely different story. Matt. > Hi John, > > It won't hold up others. > > You must be very careful of in modifying variables shared between the two > timers.
