I'm using UltraWebGridExcelExporter, and I get the messages below when I try to save the Excel file which I just opened by selecting 'Open' on the Save/Open/Cancel dialog box.  When I click 'Save' on newly created excel file, Excel usually gives me 'Save As' dialog, but for some reason I don't get 'Save AS' dialog and the Excel program seems to be trying to save the temporary file which is (probably) created by UltraWebGridExcelExporter.

I get these 3 messages after I click 'Save' button on Excel...

1) Your Changes could not be saved to 'MyCF_DG[1].XLS' because of a sharing violation.  Try saving to a different file. ->Click  OK (MyCF_DG is my UltraWebGrid name.)
2) The file you are trying to open, '9D1A300.IES\...', is in a different format than specified by the file extension.  Verify that the file is not corrupted and is from a trusted source before opening the file.  Do you want to open the file now> Yes/No/Help -> Click No
3) Your changes could not be saved to 'MyCF_DG(1).XLS', but were saved to a temporary document named '9D1A3000'.  Close the existing document, then open the temporary document and save it under a new name. -> Click OK (The help says I do not have a permission to modify or delete the file.)

After I go through all these messages and click the save button again, Excel brings me to 'Save As' dialog and I can save the file without any problem.  I am wondering why Excel does not give me 'Save As' dialong at the first time I click 'Save' button.

Thank you in advance.
