Workbook SaveAs method fails

[stevek]

Can anyone advise cause of following problem when trying to save an Excel workbook.

I have created an excel workbook in jade and populated all data.

Final step is to
workbook := theExcelApp.activeWorkbook;
workbook.saveAs(theFileName,
null, null, null,
null,
null, null, null,
null, null, null);

However this results in an activeX error of -2146827284 when the SaveAs line is executed.
I have researched the error code on the web and cannot find any reason that relates to my problem

Please ignore query.
Discovered after I rebooted the client machine, everything worked as expected.
