One of my friends is having a devil of a time with closing messages in
Mozilla Thunderbird. When she attempts to exit the message by hitting
escape to close it, nothing happens. The message remains open. A
similar thing happens when she tries to use the ctrl-W keyboard
shortcut. It either works properly, or totally exits the program. Any
ideas as to what's happening here? She's using the latest versions of
windows, and NVDA.
