Part of a worksheet is missing when you run a VBA macro that uses the ScreenUpdating property to unhide a worksheet after you close the Document Recovery task pane in Excel 2002

Consider the following scenario. You open a Microsoft Excel 2002 workbook that causes the Document Recovery task pane to open. Then, you close the Document Recovery task pane. If you then run a Microsoft Visual Basic for Applications (VBA) macro that uses the ScreenUpdating property to unhide a worksheet programmatically, the screen may not be updated correctly. Additionally, part of the worksheet is missing.

Note The part of the worksheet that is missing may appear as gray shading that has the same size and location as the Document Recovery task pane.
