I am developing an Office 2003 SmartDocument application where Excel charts in the document are to be populated with data from code.
The following code handles the update of all Excel charts in the document:

            System.Globalization.CultureInfo ciOld = System.Threading.Thread.CurrentThread.CurrentCulture;
            System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");
                foreach (InlineShape objShape in wordDocument.InlineShapes)
                    if (objShape.OLEFormat != null && objShape.OLEFormat.ClassType == "Excel.Chart.8")
                        Microsoft.Office.Interop.Excel.Workbook objWorkBook = (Microsoft.Office.Interop.Excel.Workbook)objShape.OLEFormat.Object;
                        Microsoft.Office.Interop.Excel.Application objApp = objWorkBook.Application;
                        // Some code to manipulate the workbook...
            catch (Exception e)
                MessageBox.Show("Error: " + e.Message, "", MessageBoxButtons.OK, MessageBoxIcon.Error);
                System.Threading.Thread.CurrentThread.CurrentCulture = ciOld;

Executing the code as displayed above, throws an exception (Exception from HRESULT: 0x800A03EC) in the line containing 'objApp.Workbooks.Close();' for the first chart encountered.

Omitting the call will leave the chart selected in the document hiding the Actions Pane which is NOT intended.

Am I missing something - is there a workaround - suggestions are very welcome.
