The information in this article applies to:
In Microsoft Excel 97, when you open and then close a workbook that was saved in WK4 (1-2-3) format, you may receive the following error message:
This program has performed an illegal operation and will be shut down.
If the problem persists, contact the program vendor.
If you click Details, an error message similar to the following appears:
Excel caused an invalid page fault in module <unknown> at 0000:01cf0004
This problem occurs only when you perform the following steps:
1. You group two OLE objects together on a worksheet.
2. You then save the workbook in WK4 (1-2-3) file format.
3. You then close the workbook.
4. You then reopen and then close the workbook.
To prevent this issue from occurring, do not group OLE objects if you are going to save in WK4 (1-2-3) format.
Microsoft has confirmed this to be a problem in Microsoft Excel 97.
For more information about WK4 files, click Contents And Index on the Help menu, click the Index tab in Microsoft Excel Help, type the following text
WK4
and then double-click the selected text to go to the "Troubleshoot
converting file formats" topic. If you are unable to find the information
you need, ask the Office Assistant.
