When I select an e-mail and click delete in the top panel sometimes not only the selected item is deleted, but also the one under the selected item. It means, that important mails dissappear. I have no idea how to prevent this neither how or what I did. It seems that somehow Thunderbird selects more than the selected item. I enclose two screenprints: * Selected item to delete in inbox with the to delete item in the inbox * deleted items in the map deleted, wheree you can see that also the mail beneath the selected item is deleted This really bad, since I lose from time to time important e-mails
