Method 'Save' of object '_Workbook' failed

I am creating an Excel spreadsheet from Access using VBA (Office 2002).  After I create and modify the spreadsheet I save it and get the error:

Error -2147417851
Method "Save' of object '_Workbook' failed

(edited code snippet below)
Dim objXLApp As Excel.Application
Dim objXLBook As Excel.Workbook
Dim objQuerySheet As Excel.Worksheet
Dim objResultsSheet As Excel.Worksheet
Dim objXLRange As Excel.Range
   
         DoCmd.OutputTo acOutputReport, "rptStockGoals", acFormatXLS, strPath, -1
        Set objXLBook = GetObject(strPath)
        Set objXLApp = objXLBook.Parent
        Set objQuerySheet = objXLBook.Worksheets("rptStockGoals")
        objXLApp.Visible = True
        objXLBook.Windows(1).Visible = True
<modify the spreadsheet here>
~Error occurs when the next line is executed.
        objXLBook.Save

So I create the spreadsheet from access/vba with no problem.  I open it and modify it but when I go to save it my error occurs.

This only happens for two users and only when they are logged onto their PC's.  If I log on to their PC I do not get the error.  If they log on to another PC they do not get the error.  For one of the users this code has worked until a few weeks ago.

When the error occurs a file is created (attached) in the same directory where I saved the spreadsheet.  It is named something different each time , eg. 038C3100 with no extension.

I can close the spreadsheet after the error occurs but Excel itself hangs.

If you need any further info please let me know.

Thanks
