Sorry for this very basic question and if this has already been 
answered before in this list or in the documentation but....
I have 2 main stacks in the same folder and I want to launch stack A 
which should automatically open stack B;  the 2 stacks  should be 
visible.
How can I achieve this?
Thank you for your attention and sorry for my English too but I have 
done my best here :-)
Ciao from Italy
