I blocked a large number of emails in one local folder and tried to drag them to another folder. Little circular icon on screen seemed to indicate that something was happening, but after several minutes it was still there, with no results visible. After a half hour, I just exited from Firebird. When I came back, the new local folder showed a large number of emails, but with Subject and From fields blank, and time = when I tried to move them. Clicking on any of these opens a blank screen. They are all gone from the folder I tried to move them from. Is there any way I can retrieve these?
