1. After return from the long vacation, I discovered that my old WinXP SP3+Opera doesn't support Steam authorization anymore. Something with new SSL authorization, it seems. Well, nothing too bad, Chrome still works. Unfortunately, Miranda Steam plugin stopped to work too. :/
2. Installed Open SSL plugin, as recommended. Problem with Steam plugin disappeared... but now I cannot login into Skype! (Problem disappearing if I remove Open SSL, predicably).
Is Skype plugin doesn't compatible with Open SSL plugin? Or is there something that can be done?
