--- Comment #4 from Renato Alves simpledark@gmail.com 2008-10-27 20:49:13 --- As of wine-1.1.4 the two windows still show up separately but the chat window is now kept on top of the game window as expected. It is still not anchored but is "always" visible.
The toolbar problem reported in comment #2 is no longer present. Both windows now show up in the toolbar, "Apprentice" and "fmChat".
As for Gnome testing, I haven't got access to a gnome desktop yet, I will work into that. Same for Kde. About other apps, I don't know any. But Apprentice can be freely downloaded. (I think I missed the point of the downloadable part.)
