So, with your explanation: when you hide modal form it should stay in modal 
loop and application is completelly unresponsive ?

no, it will be reached as soon as form leaves *modal loop* for any reason 
(closing, hiding).

No, FormClose() isn't called when modal form is hidden via Hide(); , so form 
still exists and it can be called with ShowModal() or Show() again.
