I found a minor bug in 2.72 (haven't checked if it occurs in 2.8 as well) - if you place the AGS editor files in the same folder as a game, then try to open that game from that folder, it doesn't work. Perhaps this is to be expected, but instead of giving a message for that, it simply repeats the "welcome to AGS" popup box.
I have no plans to fix any problems with the 2.72 editor, I'm afraid.
That's not what I meant :) I meant maybe it still occurs with the v2.8 editor, too.
