[AccessD] Modifying Replicated Database Using Access 2010

Folks,

I know there are some old timers on this list who have worked with Access
Jet Replication. Not to many folks use or even know about replication any
more since it was depreciated starting with the advent of the accdb file
format. In any case I use it where networks are slow or unreliable and it
just works. That is until I tried to maintain an replication system using
Access 2010. 

We have a system that uses replication to allow folks in two different
locations to work with a common database back end. The network is not high
quality, and slow so I used replication to put a back end at each location
and keep them synchronized. Synchronization is done through the Replication
Manager and synchronizer running on a schedule. This has been working great
for the past two years. The system was originally developed and used with
Access 2007 but with the back end in mdb format. So now the client is up to
Access 2010. The client wanted some changes to the back end, entailing some
new tables and new fields added to existing tables. No problem I think. I
went to the site and opened the Replica set design master using Access 2010
and added the new tables with no problem. Then I tried to add the new fields
to existing tables. I could do that in design view but when I tried to save
the changes I get a message 'Operation not supported for this type of
object' message. I banged my head against the wall for a while thinking I
was doing something wrong, then gave up working at the client facility. I
did run the synchronizer before leaving and the new tables propagated
properly to the other managed databases. This part is working.

After returning to my office I thought possibly this is an Access 2010
issue. I fired up a virtual machine with Access 2007 on it and a running
replication system of the same database. In Access 2007 I could open the
design master and add fields to existing tables with no errors and the
changes would save. Is this an Access 2010 issue or is there something else
going on? I'd hate to have to re-install Access 2007 on one of the client
computers to make these changes. I have the same system running on my Access
2010 machine and I can duplicate the 'Operation not supported for this type
of object'  issue using Access 2010 in my office. Any thoughts?

Thanks in advance for your assistance.

Doug
