When MySQL for Excel is installed and enabled, Excel's built-in 'Refresh All' button now causes an exception from MySQL for Excel - even if there are no MySQL data sources in the file.

How to repeat:
1 - Open a new instance of Microsoft Excel (with MySQL for Excel enabled)
2 - In the first sheet of the new book, cell A1, type 'My heading' and in cell A2 'My Data', then select the two cells.
3 - On the 'Home' tab choose 'Format as Table' and set any style, accepting that your table has headers.
4 - On the 'Data' tab choose 'Refresh All'
5 - HRESULT: 0x800A03EC is returned

Suggested fix:
I don't know enough about the system to contribute anything helpful here, but perhaps the MySQL script could check that the table is indeed a MySQL table before returning the error? Or just handle the exception?

Just so you know, I have already looked at http://forums.mysql.com/read.php?172,630324,630324#msg-630324 and http://bugs.mysql.com/bug.php?id=73467, which are both slightly different issues.

Updated to reflect that this issue is still present in 1.3.5

Fixed the way MySQL for Excel does the custom Refresh All action for Excel ListObjects, the method to refresh the ListObject when the data source is a QueryTable was incorrect.

The correct fix message is this:

Fixed a problem when Refresh All was done so that the Refresh method is not called for Excel ListObjects that have an Excel range as their data source, since that throws a COM Exception.
