Pause bug in menus with scroll bars

Pressing the pause key makes the skull cursor jump beside the scroll bars. This may be because Doom allows to type the first letter of a menu item to jump there, so the pause key may be associated with scroll bars. It also happens with Caps Lock which does the same thing, but it repeats when Caps lock is on. The scroll bar can't be scrolled when the cursor is there. It will go back to it normal if another key such as up, down or a shortcut letter is pressed. This bug is found in the sound menu and the options menu.
