This article was previously published under Q170949


After you run a macro and edit a three-dimensional pie chart, Excel for Windows 95 may stop responding, a general protection fault may occur, and the following error message may appear:

This program has performed an illegal operation
and will be shut down.

If you click Details, a message similar to the following appears:

Excel cause an invalid page fault in module
Mso97.dll at 0137:50603f25.

When you click OK, Excel closes.


This problem occurs when the following conditions are true:

  • You create a 3-D pie chart in Microsoft Excel 7.0. -and-

  • You create a macro that contains a line of code that adds the Auto_Close defined name that refers to another macro. -and-

  • The macro to which Auto_Close refers contains a line of code that deletes Auto_Close. -and-

  • You run the macro that deletes the Auto_Close defined name.

When the Auto_Close macro runs, the following error message appears:

The 3-D View Dialog code leaves internal variables set incorrectly.
When the workbook is closed, Excel 95 attempts to access an
uninitialized variable.
