The dialog resulting from choosing RegExp Help in the Find Dialog's question mark menu is only partially functional. Clicking the even items in the left-hand list does not bring up the corresponding text on the right. Also, I get nothing from the choice "Filesets Help."
This is fixed now. The proc hi::itemsSelection did not handle correctly the case of an Outline view.
