I didnt look at the collapsed property when positioning the drawings. you can download the latest source and try. I dont have the time to test it fully today. I hope I fixed the hyperlink problem as well.
Be awared of the the SetPosition and Setsize methods only sets the From and To properties of the drawing, so if you resize/hide or collapse rows and columns after you position/resize the drawing the From and To properties will be left unchanged.
You can also position the chart with the from and to properties if you dont get it to work as expected.
