Hi Harald,

well, I made a simple test and created two datamodules in two differnet
sessions. The name was not changed in any way. I stored with one session a
value and tried to read it out in another. The dataModules were really
different!

Perhaps you are describing another case? I am not using the global variable
of the TdataModule. Instead I am storing the DataModule in the associated
Session class.

I am confused,
Bengt
