When you open a Microsoft Excel 2010 workbook that contains many OLE objects, ActiveX controls, or form controls, the workbook does not work correctly.
For example, the following issues may occur:
Excel 2010 stops responding
Excel 2010 crashes
If you are running a Windows operating system, the operating system and other applications that are running on the computer are also affected.
This issue occurs because the operating system has a limit to the number of Graphics Device Interface (GDI) objects that can be created after the operating system is installed. If the operating system reaches the limit, no new GDI object is allocated. Additionally, a Windows operating system and any other running application stop responding.
