I have two bins (Trashcan) in Mozilla Thunderbird 3 since I updated from version 2

how do I delete the duplicate portlet? I have tried right-clicking the icon without any result.

have checked the properties of folders and the links to the main folder.

I am using Windows XP Home Premium.

thought reinstall thunderbird from scratch but are afraid to lose the contacts in my address book, and my email messages.

how can I best approach to solve the problem?

best regards Alexander
