[Trisquel-users] A pesky send-message window pops up whenever I try to open an instance of File Manager

[amenex]

One of the email accounts in my newly migrated Icedove has gone rogue,  
opening a
message-composing window whenever I click on a file with file manager.
It's just one of my accounts - with the correct name, title etc., but if I  
wanted
to send a message, I would use webmail on the appropriate domain's server,

How do I quiet this feature ?

Thanks,
George Langford
