searches reset when closing drill-downs

If you click on a link that pops up a window, and then you close the popup window, the search criteria should not be affected, because you never left the page.  For example, if you are in Journal Inquiry and you click on the open book to display the g/l entries, and then close that window, the search criteria should not be reset because nothing has changed in that window.

If you click on a link that takes you to another page (say the pencil to modify a transaction), the back button will return to the page with the search criteria reset.
