Yes, that works very well, and therefore I'm almost back where I started, when I manually set the database for each cursor like this:

With ThisForm.DataEnvironment

.Cursor1.Database = oApp.cDataPath + oApp.cDatabase
.Cursor2.Database = oApp.cDataPath + oApp.cDatabase

EndWith

However, I set this once and I don't have to go into it everytime the dataenvironment changes.

There doesn't seem to be any difference between setting the AutoOpenTables to False, or executing the method in the BeforeOpenTables.

Thanks for your help!
