#31 message window about connection timed out locks all other tabs.

[d00m]

seems it will be better not to show modale window Putty Fatal Error with message like: "From tab tab_name: Network error: Connection timed out" when some networks issues happened.
because this message window just locks another tabs with wotking sessions and moreover - when this message window is opened and hided behind another windows - it's not possible to open new session in new tab - it just not connecting. Only if you find and close this little message window - new tab starts to works as expected.
