Use the new registry key [41563] to the define the number of entries in a listbox up to which users can use the scroll bar. The default is 50. I.e. if, for example, SIHOT finds less than 50 hits in a search, the will be shown on one page and you can scroll through of them. If there are more than 50 hits, the listbox-paging function will become active and each page will only show as many entries in the listbox as fit into the window.
