Как правильно отлавливать минимизацию окна?
Ниже приведённый код не помогает:

...

var Min : Boolean;

...

function WinProc(WinHan : THandle; Msg : UINT; wParam: WPARAM; lParam: LPARAM): LRESULT; stdcall;
begin
 Result := DefWindowProc(WinHan, Msg, wParam, lParam);

 case Msg of
   ...  
 
   WM_SIZE    :
     If (wParam = SIZE_MAXHIDE) or (wParam = SIZE_MINIMIZED) then
        Min := True else Min := False;
   ...
 
 end;
end;

...

Тебе уже отвечали, обрабатывай WM_ACTIVATE.

The WM_ACTIVATE message is sent to both the window being activated and the window being deactivated. If the windows use the same input queue, the message is sent synchronously, first to the window procedure of the top-level window being deactivated, then to the window procedure of the top-level window being activated. If the windows use different input queues, the message is sent asynchronously, so the window is activated immediately.

Parameters

wParam
The low-order word specifies whether the window is being activated or deactivated. This parameter can be one of the following values. The high-order word specifies the minimized state of the window being activated or deactivated. A nonzero value indicates the window is minimized.
WA_ACTIVE
Activated by some method other than a mouse click (for example, by a call to the SetActiveWindow function or by use of the keyboard interface to select the window).
WA_CLICKACTIVE
Activated by a mouse click.
WA_INACTIVE
Deactivated.

lParam
Handle to the window being activated or deactivated, depending on the value of the wParam parameter. If the low-order word of wParam is WA_INACTIVE, lParam is the handle to the window being activated. If the low-order word of wParam is WA_ACTIVE or WA_CLICKACTIVE, lParam is the handle to the window being deactivated. This handle can be NULL.
