--- Comment #2 from hans_squared@yahoo.com --- According to the same poster, the editor works in Wine 1.7.2: http://www.grimrock.net/forum/viewtopic.php?f=21&t=7010&start=20#p78...
I got the editor running!
I had no idea what could possibly have been causing the black screen thing, so I just tried running it in all of my different Wine prefixes. First one it worked in was a clean Wine 1.7.2, win32. Windows version doesn't make a difference, no dll overrides. I don't know what I did to my 1.7.28 installation that broke it.
