Вот так:

unit move;

interface

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

type
TForm1 = class(TForm)
procedure FormCreate(Sender: TObject);
private
Capture: HWND;
InMove: Boolean;
MouseOffset: TPoint;
procedure WMNCLButtonDown(var Message: TWMNCMouseMove); message WM_NCLBUTTONDOWN;
procedure WMMouseMove(var Message: TWMMouseMove); message WM_MOUSEMOVE;
procedure WMLButtonUp(var Message: TMessage); message WM_LBUTTONUP;
end;

var
Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.WMMouseMove(var Message: TWMMouseMove);
var
MousePt: TPoint;
begin
if InMove then
begin
GetCursorPos(MousePt);
MousePt.x := MousePt.x - MouseOffset.x;
MousePt.y := MousePt.y - MouseOffset.y;
Left := MousePt.x;
Top := MousePt.y;
end else inherited;
end;

procedure TForm1.WMNCLButtonDown(var Message: TWMNCMouseMove);
begin
if Message.HitTest = HTCAPTION then
begin
Capture := GetCapture;
SetCapture(Handle);
GetCursorPos(MouseOffset);
MouseOffset.x := MouseOffset.x - Left;
MouseOffset.y := MouseOffset.y - Top;
InMove := True;
end else inherited;
end;

procedure TForm1.WMLButtonUp(var Message: TMessage);
begin
if InMove then
begin
if Capture = 0 then ReleaseCapture else SetCapture(Capture);
InMove := False;
end else inherited;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
InMove := False;
end;

end.

Удачи.
