I've installed the software but does not work.

Menus 'view inbox' and 'tell me again' show the message proxy error near each account. I try to write proxy manually (same as firefox and ubuntu in vbox) but does not solve. I try to check 'use internet explorer settings' but it does not save the checbox state. In fact, at next attempt, the checkbox (internet settings) appears empty.

'compose' option opens the browser without logging in.

'check mail now' option does nothing

What I'm doing wrong ?

I have not a firewall or any other antivirus running.
