I apologise to those who find this query shockingly off topic. If anyone cluey cares to send me an off-list response, I'd be grateful - everyone else should delete right now.
Every now and then, as Eudora Pro on my old Windows 3.x downloads it gets into a strange mood and pastes in a little green garbage bin on feet, or something like that, in every single In Mail message notification, in a column headed V to the left of the Subject column. This does nothing obvious except hold up the download, sometimes locking it up. Any clues? (I can't find a hint in Eudora's Help file, under V for example, but maybe I need the right head-word as a clue. I tried their on-line FAQ and Search facility, but everything just stares back at me with dumb resentment.)
