Hi,

I've not seen it happen in all circumstances, but I have seen strange things occur when you change the datasession manually and don't put it back where you found it.

So you're referring to cases where code which is expecting a specific datasession is executing with a different one set ? I'd certainly expect problems in that scenario - however (begging the question of why anyone would do it <s>) I've not seen problems when releasing a form when it's datasession is changed after it has been instantiated.

Guess all I'm really trying to pin down is how an 'Unknown' datasession comes about.
