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 b
Have tried this using latest version on Windows 7 and Windows XP, and can't replicate this.
You need to have an existing SSL POP3 connection which fails. It does not happen without SSL.
This happens to me with or with out the icon in the system tray and it happens with NO SSL. Every time it downloads messages. Windows 7 x64 Clawsmail 3.9.1
