I have form on which is button. When user clicks button OnClick event

In the background is operating another thread which every 10 seconds
calls Synchronize(@MyForm.MyMethod).
My understanding is that, Synchronize schedules execution of
MyForm.MyMethod to main thread, so method is not executed until
control is returned from event handler in MyForm. Right?
If you don't call CheckSynchronize within MyForm.MyMethod then yes.
But in my case happens, that method is executed while execution of
event handler does not finished yet ... is it expected behavior ?
If not is there any workaroud which enables me to hold thread until
event handler finishes ?
Check for Application.ProcessMessages and CheckSynchronize calls. These
process synchronize queue, if I am not mistaken.
