Delphi de bilmiyorum ama c# da TThread.Sleep komutu çalışırken programın tüm fonksiyonları devre dışı kalır yani programı komple donduruyor diye biliyorum timer ise programı dondurmadan çalışıyor diye biliyorum.

aynen öyle MainThreadı durduruyorsun bu durumda kullanıcı girişlerini yakalayamazsın bu sleepi 5 saniye ve üzerinde olursa windows tarafında not respondinge düşersin
