From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.1a) Gecko/20020611 BuildID: 2002061104 After deleting a message or a group of messages, subsequent attempts to delete multiple messages will fail. However, if you delete one message and then attempt to delete another single message, the messages will be succesfully deleted up until you attempt to delete multiple messages. After the failure occurs, mozilla must be restarted before it will again allow the deletion of messages. Reproducible: Always Steps to Reproduce: 1.Open Mail & Newsgroups client 2.Select two messages by ctrl-clicking them. 3.Delete them by clicking the 'delete' button. 4.If the messages were succesfully deleted (which does not always occur), attempt to delete another group of multiple messages. Actual Results: Status bar reads 'Moving x of x messages to Trash' and status indicator icon in upper-right hand corner indicates activity, but no messages are deleted. Expected Results: Mozilla should reliably delete any number of messages at any time.
