just wanted to share some information (which is of cource not official) regarding X-Chat Aqua 0.17.0-rc1 and compatibility to Mac OS X 10.6 (Snow Leopard). You can grab your copy of X-Chat Aqua either here http://www.uplinklabs.net/~tycho/projects/xchat-aqua/ or here http://verloren-im.net/dl/X-Chat_Aqua_0.17.0-rc1.zip
For me this combination works perfectly. The Issue #1989087 (Spaces Issue) seems to be fixed somehow - on Leopard I've encountered the same thing sometimes. Now it openes in any situation on the correct Space.
So long ..
Thanks for reviving the project.
