Thanks my funny russian English ) But I hope you got my thought)
Oh I'm not making fun of your English or something, I'm making fun of check box what should return true if checked and false when unchecked.
In this case this not make any sense.
Delayed drawing of the execution process = checked = true -------- There is not delayed drawing
Delayed drawing of the execution process = unchecked = false -------- There is delayed drawing
That was my point
