First off, let me show you my code for the camera movement,

void camera_movement()
{
	dbPositionCamera(dbObjectPositionX(3),dbObjectPositionY(3),dbObjectPositionZ(3));
	dbPositionObject(3,dbObjectPositionX(1),dbObjectPositionY(1) + 2,dbObjectPositionZ(1));
	int XAngleCamera = dbObjectAngleX(3);
	int Max = dbObjectAngleX(3) + dbMouseMoveY() / 2;
	if ( dbMouseClick() == 2 )
	{
		int fmx = dbMouseX();
		int fmy = dbMouseY();
		dbHideMouse ();
		dbXRotateObject(3,Max);
		dbRotateCamera(dbObjectAngleX(3),dbObjectAngleY(1),dbObjectAngleZ(3));
		dbRotateObject( 1, 0, dbObjectAngleY(1) + dbMouseMoveX() / 2, dbObjectAngleZ(1) );
		dbPositionMouse (fmx, fmy);
		if (dbKeyState(30)) // A straffe left
		{
			dbMoveObjectLeft(1,.25);
		}
		if (dbKeyState(32)) // D straffe Right
		{
			dbMoveObjectRight(1,.25);
		}
	}
		dbMoveCamera( -15 );
	if ( dbMouseClick() == 0 )
	{
		dbShowMouse();
		if (dbKeyState(30)) // A straffe left
		{
			dbRotateCamera(dbObjectAngleX(3),dbObjectAngleY(1),dbObjectAngleZ(3));
			dbRotateObject( 1, 0, dbObjectAngleY(1) - 3, dbObjectAngleZ(1) );
		}
		if (dbKeyState(32)) // D straffe Right
		{
			dbRotateCamera(dbObjectAngleX(3),dbObjectAngleY(1),dbObjectAngleZ(3));
			dbRotateObject( 1, 0, dbObjectAngleY(1) + 3, dbObjectAngleZ(1) );
		}
	}
}

+ Code Snippet

void camera_movement()
{
	dbPositionCamera(dbObjectPositionX(3),dbObjectPositionY(3),dbObjectPositionZ(3));
	dbPositionObject(3,dbObjectPositionX(1),dbObjectPositionY(1) + 2,dbObjectPositionZ(1));
	int XAngleCamera = dbObjectAngleX(3);
	int Max = dbObjectAngleX(3) + dbMouseMoveY() / 2;
	if ( dbMouseClick() == 2 )
	{
		int fmx = dbMouseX();
		int fmy = dbMouseY();
		dbHideMouse ();
		dbXRotateObject(3,Max);
		dbRotateCamera(dbObjectAngleX(3),dbObjectAngleY(1),dbObjectAngleZ(3));
		dbRotateObject( 1, 0, dbObjectAngleY(1) + dbMouseMoveX() / 2, dbObjectAngleZ(1) );
		dbPositionMouse (fmx, fmy);
		if (dbKeyState(30)) // A straffe left
		{
			dbMoveObjectLeft(1,.25);
		}
		if (dbKeyState(32)) // D straffe Right
		{
			dbMoveObjectRight(1,.25);
		}
	}
		dbMoveCamera( -15 );
	if ( dbMouseClick() == 0 )
	{
		dbShowMouse();
		if (dbKeyState(30)) // A straffe left
		{
			dbRotateCamera(dbObjectAngleX(3),dbObjectAngleY(1),dbObjectAngleZ(3));
			dbRotateObject( 1, 0, dbObjectAngleY(1) - 3, dbObjectAngleZ(1) );
		}
		if (dbKeyState(32)) // D straffe Right
		{
			dbRotateCamera(dbObjectAngleX(3),dbObjectAngleY(1),dbObjectAngleZ(3));
			dbRotateObject( 1, 0, dbObjectAngleY(1) + 3, dbObjectAngleZ(1) );
		}
	}
}

Now my issue is somewhat small but an annoying one at that, it seems as if every time I Right-Click after I have moved the mouse at all it snaps to that position (as if you were holding the right click in and moving the mouse but it only updated the view after you let go) I can see in the code WHY this is happening, but im not sure what to do to stop it from happening.

Thanks for your input!!

I would like to repost the code I have so far, for my camera controls, since the issue is still there i've just moved onto other things that neec accomplished. =]

Main Camera Function:

+ Code Snippet

void Camera_Control()
{
	int Max	= dbObjectAngleX( 4 ) + dbMouseMoveY() / 3;

	dbPositionCamera ( dbObjectPositionX(4), dbObjectPositionY(4), dbObjectPositionZ(4) );
	dbPositionObject ( 4, dbObjectPositionX(3), dbObjectPositionY(3) + 2, dbObjectPositionZ(3) );
	dbMoveCamera	 ( -10 );
	dbRotateCamera	 ( dbObjectAngleX(4), dbObjectAngleY(3) + 180, dbObjectAngleZ(4) );

	if ( dbMouseClick() == 2 )
	{
		dbHideMouse		( );
		dbXRotateObject ( 4, Max );
		dbRotateObject	( 3, 0, dbObjectAngleY(3) + dbMouseMoveX() / 3, dbObjectAngleZ(3) );
	}
	dbShowMouse();
}

Function that actually sets up the object 3 and 4:

+ Code Snippet

void Setup_Player()
{
	dbLoadObject	   ( "H-GI-Static.x", 3 );
	dbPositionObject   ( 3, 260, 260, 200 );
	dbMakeObjectSphere ( 4, 1 );
	dbScaleObject	   ( 4, 10, 10, 10 );
	dbPositionCamera   ( dbObjectPositionX(4), dbObjectPositionY(4), dbObjectPositionZ(4) );
	dbPositionObject   ( 4, dbObjectPositionX(3), dbObjectPositionY(3) + 2, dbObjectPositionZ(3) );
	dbMoveCamera	   ( -10 );
}

Oh and setup_player is being called first and only once. Where as camera_control is called every frame.
