I have already set the datasession to 2-private, but it doesn't work.

let me explain to you :

I have only one form but I want to open the form more than one because each form
was filtered with some filter condition, for example :

- I open the form with this condition : Set filter to Sales='1997'..
- I minimize the form and I run it again but with other conditon for eg.
Set filter to Sales='1998' ..

The problem is : when I go back to the 1st form ( filtered with sales='1997' )
filtered condition was changed with the last form (sales='1998')

pf. the form contains the grid control


can you explain to me, please ..?
