When I highlight unwanted messages and then click "DELETE" in Toolbar, I get box saying "unknown command received". After a minute or so, the box information changes to "Deleting messages", shown in a shaded progress bar type of band. However, the process deems endless. A "cancel" button is available in the box, but seems to be useless. I find the only way to halt the hang-up is to go to Task Manager and kill Live Mail.

It appears Live Mail is corrupt. Should I try to do a new download? What is the danger to stored messages and contact list?
