I've two opened Databases with different master key's, one of them I syncronize with a copy located on a shared drive with a trigger on open, save and close of database.
Until 2.22 everything works fine, from 2.23 on I get an error Message "The composite key is invalid! Make sure that the two databases use the same composite master key. This is required for synchronization."
The two databases I sync have the same key, but the two I've opened have different ones.
When I change the Master Key of the not syncing DB to the same of the synced DB than I got no error message.
In my oppinion this is a bug from 2.23, because until 2.22 all was fine.
