Answer 1

i solved the issue. it was a matter of reordering the logic flow.

the solution spans 3 mouse events MouseEnter, MouseMove, MouseLeave.

    private PictureBox HomeLastPicBox = null;

    private TableLayoutPanelCellPosition HomeLastPosition = new TableLayoutPanelCellPosition(0, 0);

    private void HomeTableLayoutPanel_MouseMove(object sender, MouseEventArgs e)
    {
        PictureBox HomeCurrentPicBox = (PictureBox)(HomeTableLayoutPanel.GetChildAtPoint(e.Location));

        if ((HomeCurrentPicBox != HomeLastPicBox) && (HomeCurrentPicBox != null))
        {

            HomeLastPicBox = (PictureBox)HomeTableLayoutPanel.GetControlFromPosition(HomeLastPosition.Column, HomeLastPosition.Row);

            if (GameModel.HomeCellStatus(HomeLastPosition.Column, HomeLastPosition.Row) == Cell.cellState.WATER)
            {
                HomeLastPicBox.Image = Properties.Resources.water;

            }

            TableLayoutPanelCellPosition HomeCurrentPosition = HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox);

            if (GameModel.HomeCellStatus(HomeCurrentPosition.Column, HomeCurrentPosition.Row) == Cell.cellState.WATER)
            {
                HomeCurrentPicBox.Image = Properties.Resources.scan;

                HomeLastPosition = HomeCurrentPosition;
            }

            gameFormToolTip.SetToolTip(HomeTableLayoutPanel, GameModel.alphaCoords(HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox).Column) + "," + HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox).Row);
        }
    }

    private void HomeTableLayoutPanel_MouseEnter(object sender, EventArgs e)
    {
        Point p = HomeTableLayoutPanel.PointToClient(Control.MousePosition);
        PictureBox HomeCurrentPicBox = (PictureBox)(HomeTableLayoutPanel.GetChildAtPoint(p));

        if (HomeCurrentPicBox != null)
        {
            TableLayoutPanelCellPosition HomeCurrentPosition = HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox);

            if (GameModel.HomeCellStatus(HomeCurrentPosition.Column, HomeCurrentPosition.Row) == Cell.cellState.WATER)
            {
                HomeCurrentPicBox.Image = Properties.Resources.scan;
            }

            gameFormToolTip.SetToolTip(HomeTableLayoutPanel, GameModel.alphaCoords(HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox).Column) + "," + HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox).Row);
        }
    }

    private void HomeTableLayoutPanel_MouseLeave(object sender, EventArgs e)
    {
        if (GameModel.HomeCellStatus(HomeLastPosition.Column, HomeLastPosition.Row) == Cell.cellState.WATER)
        {
            HomeLastPicBox = (PictureBox)HomeTableLayoutPanel.GetControlFromPosition(HomeLastPosition.Column, HomeLastPosition.Row);

            HomeLastPicBox.Image = Properties.Resources.water;

            gameFormToolTip.SetToolTip(HomeTableLayoutPanel, GameModel.alphaCoords(HomeTableLayoutPanel.GetCellPosition(HomeLastPicBox).Column) + "," + HomeTableLayoutPanel.GetCellPosition(HomeLastPicBox).Row);
        }
    }

i thought i would post the solution for future knowledge seekers.

thanks.
