If the checkbox is checked the loop should run, if it is unchecked no action. I tried this with onClick:

Something like that should never be done in an "Event driven" system 
like a Lazarus application.

Each event should be finished (ad the handler procedure exited) as fast 
as possible.

So you should exit the procedure when the check box is not checked and 
start a new execution in the "CheckBox1Change" event.
