Whenever I want to set the window on or off, all I'm left is a black screen. I don't know if this is a bug or just me. Please take a look at the example. Keys to set window are F3 and F4.

+ Code Snippet

#include "DarkGDK.h"
void DarkGDK ( void )
{
	float a=0;
	dbSyncOn ( );
	dbSyncRate ( 60 );
	dbSetWindowTitle ( "My C++ application" );
	dbMakeObjectCube ( 1, 100 );
	while ( LoopGDK ( ) )
	{
		dbYRotateObject ( 1, a );
		dbSync ( );
		a=a+1;

		if (dbKeyState ( 61 ) == 1)	// Key is 'F3'
		{
			dbSetWindowOn();
			dbSetWindowLayout ( 1, 1, 1 );
		}

		if (dbKeyState ( 62 ) == 1)	// Key is 'F4'
			dbSetWindowOff();

	}
}

I tried this in DBPro too and it crashes. object no longer exists.

So I'm guessing SetWindow flushes the video memory, is there anyway around this?

I believe you have to reload all your objects, images etc after changing between fullscreen and windowed
