I developed an Excel Workbook that has VBA to automate certain processes. It
works without any issue in 2003.

Now we have moved to 2007 and for an unknown reason the code now spits out
'error: 9', several times.

The code still run and the result is correct?! Should I simply ignore the
error statements or should they be adressed?

Is this a known issue by any chance or do I need to rip apart my code to
resolve it?

Thank you for your advice,

QB
