Long time ago, I've reported a bug - blacklisting doesn't work for certain full-screen applications (mostly games, frogatto, to name one from top of my head). CSSU developer of blacklisting methods (I don't remember, who was that - I contacted MAG first, and MAG redirected me to mentioned person) said that bug is valid, and fix will be introduced in next update. Unfortunately, it's still rorating, despite being blacklisted both in transitions.ini and special entry in .desktop file. I'm not complaining, but would like to know - was fixing it just delayed, or it should work flawlessly now, but doesn't? /Estel // Edit Of course blacklisting as whole works for me - it's just matter of some programs, exactly the same I reported long time ago. I'm sure that I haven't introduced any typos in application name/ .desktop file etc.
