Problem.....

If I create more than 9 files - system halts when I scroll list DOWN.

The program halts during the execution of scrollList1UpdateItem() that is called for no apparent reason. is this normal? I don't update the elements, but for some reason when scrolling down scrollList1UpdateItem is called.

Should it be called while scrollin DOWN?
