Very large libraries still have the option to run the resource intensive overdues.pl with no filters, even when the syspref is on to require filters before running it. I propose a confirmation message to ensure users know that the thing they are requesting is very resource intensive and may not complete, as we don't want to take away the functionality but I do think people should really be sure they know what they are doing when they click through with no filters on this page. Other solutions to this problem welcome - my requirements are - the option to run the full report should still be available, as it is now - users should be duly warned and forced to confirm that they really want to do this when the no-filter case is requested.
