As a joke, I am trying to have a button on a form move around the form to avoid the 
mouse pointer. I was trying to use the OnMouseMove event of the form to accomplish 
this, but have not had any success. Does anybody know a quick way of doing this?

Answer:

1   procedure TMainForm.Button1MouseMove(Sender: TObject; Shift: TShiftState; 
2   X, Y: Integer);
3   var
4     NewPoint: TPoint;
5   begin
6     Randomize;
7     NewPoint.X := X;
8     NewPoint.Y := Y;
9     repeat
10      NewPoint.X := NewPoint.X + Random((Sender as TButton).Width div 2);
11      NewPoint.Y := NewPoint.Y + Random((Sender as TButton).Height div 2);
12    until
13      PtInRect(ClientRect, NewPoint) and not PtInRect((Sender as TButton).ClientRect, 
14  NewPoint);
15    (Sender as TButton).Left := NewPoint.X;
16    (Sender as TButton).Top := NewPoint.Y;
17  end;
