I use the IRC protocol a lot and tend to speak with many random people and join various channels throughout a day etc.
If you don't have the 'Delete temporary contacts when closing message window' option checked under the Message Session tab, every person you speak to and every channel you join will continue to be added to your Contact List.
Long story short is I realized today that since 0.40 or 0.41 this feature is no longer working correctly and was wondering if anyone is experiencing the same problem?
I tried relaunching Miranda as well as checking/unchecking that option.
Miranda Version: 0.41
