New form acts weirdly on taskbar

Im using a button to switch from one form to another. Quite simply:

procedure TStep1.NextStepClick(Sender: TObject);
begin
 Step1.Hide;
 Step2.Show;
end;

However, the new form acts weirdly on the taskbar. It has no name on
the taskbar (it has a caption) and when you minimize it FROM the
taskbar (not using minimize buttons) - once it goes down you cant get
it back up.

I want Step1 form to go from the taskbar and Step2 to appear on it.

How can this be done? I tried using this (online source):

protected
   procedure CreateParams(var Params: TCreateParams); override;

procedure TStep2.CreateParams(var Params: TCreateParams);
begin
  inherited CreateParams(Params);
  Params.ExStyle := Params.ExStyle or WS_EX_APPWINDOW;
end;

This creates a working taskbar button for Step2 but the weird non-
working taslbar button is still there.

Help!
