OK, so I'm majorly restricted right now and it's not obvious where the blame might lie, but I suspect it's to do with @startim=n
While in this state I received a texture from someone with whom I wasn't in an IM conversation; the texture went to inventory and I have a Notice saying I have an Inventory offer from the av. That's all to be expected.
The oddity is that I cannot delete that notice. If I click on the text of "Inventory Offer" a little black box opens up on my screen. If I click on the x (for that notice), nothing happens. I can delete other notices, just not the one about the inventory offer.
