Issue about adding Vobjects and selecting area

Dear sirs,

we want to load an image. After this we want add some annotations(rectangle, lines, etc). After this we want to select an area and de-select it and add some extra more rectangles. But here we have a problem. Please see attached file that shows what the problem is.
First load a file, then add a rectangle, then add an ellipse from toolbar. After this, press the Select area button. now you can select an area.
Please notice that after selecting area, when resizing the area it appears another rectangle that comes from VObjectsRubberband1!!!
Anyway, now press button De-select area so we return to add some more rectangles. Add some and then press again Select area button and now suddenly all annotations disappears, and appears when you press De-select button!!!!

Please notice that in all annotations we have we use the .connect method because we want to see the annotations while selecting an area.

Any idea what we have to change, so we add annotations, select area, deselect area, add more annotations and select area again without losing all previous annotations?

Ok Alex, i changed BitmapViewerControl with MultilayerViewer.
Using BitmapViewer i could have access to .bitmap and all its properties and methods, in many parts of code, like

1) cropTransform.ApplyTransform(bitmapViewerMainView.Bitmap, selectedAreaBitmap)
2)selectedAreaBitmap.Draw(bitmapViewerMainView.Bitmap, rectangleRubberbandSelect.Rectangle, Aurigma.GraphicsMill.Transforms.CombineMode.Copy, 1.0, Aurigma.GraphicsMill.Transforms.InterpolationMode.HighSpeed)
3)If bitmapViewerMainView.Bitmap.IsRgb Then ....
4)bitmapViewerMainView.Bitmap.Width * 2
5)bitmapViewerMainView.Bitmap.Statistics.GetSumHistogram(New Boolean() {True, False, False, False})
....
....
....
and many many other cases. Now, after removing the BitmapViewer and instead inserting a MultipleLayerViewer, we get errors('Bitmap' is not a member of 'Aurigma.GraphicsMill.WinControls.MultilayerViewer'.) everywhere because for sure it cannot access now the .Bitmap and all its properties and methods cause does not exist?
Where is the .Bitmap in MultipleLayerViewer? Or is it something completely different and we need somehow to change everything in our code?
