SOLVED: SWITCH-TYPE ITEM ACTIVATION PROBLEM

I wrote this little problem solution for future reference and posted it to my blog. I didn't find the same solution on these forums, so I decided to post it here, too. Maybe it will help someone, or maybe someone will have further information about the issue.

PROBLEM:
I have a "Switch"-type item, Rock Innards, which are currently usable only on the map screens. The player should be able to use the Rock Innards during a battle. So, on the Item screen, I checked the box to allow item activation during battle. However, when I tested this, the item remained unavailable during battle.

SOLUTION:
RM2k3 allows various types of items. Rock Innards are a "Switch"-type item. This item type is not, apparently, useful only to certain characters. By comparison, a "Skill Scroll" item can only be used by certain characters, and RM2k3 asks you to designate which characters on the item screen for such an item. It doesn't ask you this for a "Switch" item. However, for a "Switch" item, RM2k3 is secretly carrying over the "Usable By" information from the item screen that would appear if that "Switch" item were, say, a "Skill Scroll" item. So, in order to make my Rock Innards usable during battle, I not only had to check the "Battle" activation box, I also had to temporarily set my item as a "Skill Scroll" item (or a "Seed" item or any other with a "Usable By" setting) and check that my hero ("Tom Wilson") can use the item; then I set the item back to a "Switch"-type item. This solved the problem.
