Wie sieht denn deinen Unit aus?

Ich habs mal getestet und bei mir läufst Super!

Delphi-Quellcode:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    Edit1: TEdit;
    procedure FormCreate(Sender: TObject);
    procedure FormDestroy(Sender: TObject);
  private
    { Private-Deklarationen }
    procedure AppOnMessage(var Msg: TMsg; var Handled: Boolean);
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

var 
  FConnected: Boolean; 

procedure TForm1.AppOnMessage(var Msg: TMsg; var Handled: Boolean); 
begin 
  if FConnected then
    case Msg.Message of 
      WM_KEYFIRST..WM_KEYLAST:     // Keyboard events
        Handled := True
    end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Application.OnMessage := AppOnMessage;
  FConnected := True;
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin
  Application.OnMessage := nil;
end;

end.
