Well, MAX could be the number of possible DataSessions, I don't remembr how many that is. But consdiering how slow it is, you may want to drop it down ot a more reasonable number, 100 or 1000.

>I know that the current datasession I'm in is datasession #1 but as you guess I'm having an error telling me it cannot close datasession #X, X is usually 2

This is usually because of a Dangling Object reference or because a table is open in that DS tha can't be closed because a uniquness error or something like that.
