v15.19 - Hotkey Overrides Map Scrolling Function

I have my Down Button Hotkey programmed to Screenshot.  When I have a map displayed and want to Zoom/Pan, holding the Down button, a screenshot is taken instead of performing a fast zoom/pan function.  Holding the menu button while in zoom/pan mode doesn't enter the menu, it fast zooms/pans as expected.  The hotkey shouldn't override the fast zoom/pan function.
