New Post: Real Time tracking

I am trying to update positions on the map (that are changing) in Windows forms. I have tried to do this by having a timer fire every second and reload the new markers. It works but when I try to move or zoom the map it freezes and the program has to be restarted. I have tried to stop the timer when a zoom or a move is started but I cannot find a way of detecting when the map is ready to receive updates again. I have tried waiting until the onTileLoadComplete but that does not seem to work as I think it fires before all tiles are reloaded.

What is the best way to do this?

Thank you in advance.
