In Excel 07 I open a workbook. Save it as a .xlsm workbook. Close it. When
I try to open it back up I get this message:
Excel cannot open the file 'myfilename.xlsm' because the file format or file
extension is not valid. Verify that the file has not been corrupted and the
file extension matches the format of the file.
What is causing this? I tried saving it to different locations and I get the
same error.
