I posted this in the forum, but haven't heard anything. Right now I'm trying to confirm what I think is a reproduceable bug, whereby performing an action on a multi-selected group of messages breaks multiple selections until the folder list is refreshed. This shows up in both Win/Firefox 1.5/2.0 and Win/MSIE 6.0:
The error is resolved as soon as you click on the folder name in the Folder list.
Can anyone confirm this? (If so, I'll start working on a fix.)
Thanks, Arsenio
