I agree with the previous poster: the performance of the new Webmail application is poor!
1) Terribly slow to load and initialize.
2) No setting or option to "Empty Trash" on logout of a session. As a result, messages I delete keep building up in the trash folder until I manually empty it: a definite step backwards.
3) I enabled the check boxes so I could easily select messages for mass deletes, a task I did with no problems under the previous Webmail. However, now, after the group of checked messages is deleted from the Inbox, the check box of one of the messages I'm keeping remains checked: I have to manually uncheck it to avoid inadvertently selecting it for a new action. All check boxes should be empty after I've acted on the ones I selected.
