minimizing gl window

The processor should be at 100% while the program is running. When you minimize it you''ve not changed anything.

i''m a very beginner so i might be wrong but there is [active] variable which determines if program is active or not. When [active] is zero no drawing is being performed ( i understand it this way ) :

//if ((active && !DrawGLScene()) || keys[VK_ESCAPE])//
( assuming that checking conditions is done from left to right, doesn''t it? )

so what''s going on with that processor usage?

btw: when window is active my processor usage is about 5% but when i minimize it usage raises to 100%

Something must be wrong but what?

Actually it has, why render if the app is minimized? What changed is the user minimized for a reason and the reason isn''t to have the app still rendering.

It should be something like this:
In your message procedure have something like this:

case WM_ENTERSIZEMOVE:
    Active = false;
    break;
//

case WM_SIZE:
    if(Windowed)
    {
        if(wParam == SIZE_MAXHIDE || wParam == SIZE_MINIMIZED)
	{
	    Active = false;
	}
	else
	{
	    Active = true;
	}
    }
    break;
//

case WM_EXITSIZEMOVE:
    Active = true;
    break;

Then in the message pump have something like this:

BOOL RecievedMessage;
MSG  Message;

PeekMessage(&Message, NULL, 0U, 0U, PM_NOREMOVE);
while(Message.message != WM_QUIT)
{
    if(Active)
    {
        RecievedMessage = PeekMessage(&Message, NULL, 0U, 0U, PM_REMOVE);
    }
    else
    {
        RecievedMessage = GetMessage(&Message, NULL, 0U, 0U);
    }
//

    if(RecievedMessage)
    {
        TranslateMessage(&Message);
        DispatchMessage(&Message);
    }
    else
    {
        if(Active)
        {
            Render();
	}
	else
	{
	    WaitMessage();
	}
    }
}
//

return (int)Message.wParam;

That should take it to 0% when the app gets minimized.

BTW:
//if ((active && !DrawGLScene()) || keys[VK_ESCAPE])//
( assuming that checking conditions is done from left to right, doesn''t it? )

Yes, it checks each condition from left to right. What your basically saying is:
"If my application is active and rendering the current scene returned false or the escape key was pressed then ...(Close the application?)"
