I think I see what you are saying. You have a session(for example) that you display 10 records, but have 20 records in the whole set. Then you want to select for example record 5 and record 19, and when you scroll to record 19 you lose where you selected record 5. I never really dug in a way to solve it in 4c4, but maybe someone has a solution for LN.
My latest mantra - make sure you have latest stpapi patches and the latest session object. If on LN then please explore the option of using DAL2 functionality.
