MySQL ODBC connector forgets password and server name

[Horst Wieland]

Starting with V.8, in some environments the ODBC Connector allways appears to forget it's parameters for Sytem DSNs, despite these are written into HKLM\Software\ODBC correctly.

The server name and the password are written into the data source key after having defined them. The data source works fine then.

With certain installations recalling the data source by ODBCAD32 does not present those two values, which had been defined previously, despite the key still holds these. When trying to test the connection by the GUI right after opening the data source it fails, unless the server name and passwort got redefined inside the UI.

This only happens with certain environments.
What might be wrong with these?

I recently also was confused, the data source cannot be configured to "enable auto reconnect" or use a disinct charset any more. But that was clearly announced.
It's confusing though, the GUI still offers those options even with the newest connectors, but does not use them any more and removes those registry values accordingy when saving.
