I'm assumining it's well known that containers only seem to display a certain amount of items, even if they hold more. You usually then have to exit the menu, and sometimes it seems the cell, to get the rest to display. I've also noticed this happens with the players inventory as well. Are there any mods out there that "fix" this issue, or is it simply not possible? This is one of the most annoying things about Oblivion in my eyes, as I like to collect armor/weapon sets and hold onto more valuable enchanted items.
