I have created an application on Delphi 7. my app had running fine since yesterday. I don't know what's happened yesterday which cause my application halts on Application.Initialize line in source code and does not return to next line when i trace the program. I can't run the created executable file from widows niether while the generated file does run on another machine correctly. here is the code where the compiler stops on it:

program Info_Kiosk;

uses SysUtils, Forms, ... (some other units) ;

{$R *.res}

begin
Application.Initialize;

Application.CreateForm(Tfrm_Main, frm_Main);

any help would be appreciated
