Fred,

I have already put this code in the BO's Destroy Event:

This.oDataLayer = NULL

Still, it doesn't work. Is that 'enough'?

I tried to do the following: I intentionally did not put any object reference on the BO.oDataLayer, which obviously resulted in an error. Upon closing the form, and checking on DataSession window, it released properly! So this means that it is the aberration is due to the oDataLayer object reference?

Thanks! And more help please!

Dennis
