So... I fixed it. By accident.

I remembered that there were variants available for the bags, so I switched to the non-default variant. Started playing. Clicked an item in the bag affected - and it worked fine.

Swapped back, worked fine. I even checked all my other bags in the last few slots or first few slots. Somehow, loading the variant managed to kill the bug. So the only thing I can think of is that something wasn't interacting right with the GU for AoD and by changing the UI file (via variant) the interaction was reset.

Edit to add: Okay, so I just tried to work with some bag space I hadn't tested, now right-clicking on the first row of my first two bags interacts with my Beastlord Bar. The pop-up is on the bar itself, not at the bag location, but I can't use the 'optional titlebar' variant (the default) to change those bags to completely sellable/unsellable, adjust sizes, etc. Ah, one problem down, one new one up. I'm going to switch to the variant again to see what else happens.

Second edit: I swapped the BL bar from minimized to full and it appears all is well again, for the nonce.
