More about the subway bug - when I click on the door of a for sale apartment (was in Louise Pasture) and select 'view the realty listing' nothing happens - so it seems this is related to the subway bug where I click on 'buy a ticket' and it doesn't actually buy it (currants don't go down). But the piggie problem (runs away every time on trying to capture) doesn't involve one of these dialog boxes. I'm using FF 4.01 on Win 7.
