Thank you for your reply, it is much appreciated.

As I mentioned that no longer works.

After a lot of messing around I was able to close Firefox and I now have 
Thunderbird in a reduced window size, I cannot maximise, minimise, or 
move  the Thunderbird window. The Microsoft window is now under the 
Thunderbird window.

I cannot move the Thunderbird window and so I cannot access the Whisper 
menu. This means that I cannot access any other applications including 
my password safe, backup application or a terminal window. I cannot move 
this composer window either.

It seems to me that I should be able to get the system back to normal 
after booting into rescue mode but I'm reluctant to mess around with 
something that I don't fully understand. At least I can use Thunderbird 
to ask for help but nothing else.

My system was working perfectly until I tried to use an updated SDR 
application.

Any suggestions from anyone will be greatly appreciated.
