I have a customer with a mixed Access version 2000, 2007 and 2010 network recently showing what look like incompatibility issues.
Once a 2010 user simply saves a shared network file, simple VBA code on a 2000 box opening a form fails.
I have also noticed similar but perhaps more expected issues when I modify a report in a 2003 file in 2010 and then attempt to use the MDB again on 2003.
Anyone else seeing this ?
