           Summary: claws freezes whenever it encounters POP3 error while
                    hidden in notification area
           Product: Claws Mail (Windows)
           Version: 3.8.0
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P3
         Component: default
        AssignedTo: users at lists.claws-mail.org
        ReportedBy: j.blechta at tiscali.cz


When Claws is hidden in a notification area (i.e. it has no button in task bar)
and POP3 error happens, Claws freezes, taking 100% time of 1 CPU core and
cannot be anymore used. Only possible solution is halting it and running again.
It can stay in this freezed state for hours.

It seems that same error causes alert window only and it does not freeze when
Claws is not hidden in notification area but has classical window (even
minimized) and corresponding button in task bar.

It was achieved with SSL POP3 (unblocking and blockig both). It has occured
many times and was seen on versions 3.7.8cvs47 and 3.8.0cvs30.

Here's log from freezing condition described above
[02:50:33] POP3< +OK 968 37326385
[02:50:33] POP3> STAT
[02:50:33] POP3< +OK 968 37326385
[02:50:33] POP3> UIDL

And this is log from unfreezing condition described above
[03:14:21] POP3< +OK 968 37326385
[03:14:21] POP3> STAT
[03:14:21] POP3< +OK 968 37326385
[03:14:21] POP3> UIDL
[03:14:21] *** error: Nastala chyba bìhem zpracovávání pošty.

Last line is in Czech and means "error: Error encountered while processing
messages."
