Have you been hiding them with transparent images? A better way is to relocate them out of the screen. You can do so by editing the <Inventory> section of the menu.cfg file in /config.
TinderboxesCenter = "720 127 1"
TinderboxesLabelCenter = "728 171 1"
TinderboxesFrameSize = "100 90"
TinderboxesFrameHPadding = "0 0"
TinderboxesFrameVPadding = "0 0"
TinderboxesFrameOffset = "-28 -15 1"
Make the center something like 10000 10000 1. Don't remember what the last one was, but it might actually be the visibility, so maybe putting 0 is enough.
