I used Crossover Office 5.0.3 to install whatever version of Libronix comes with the Luther's Works CD from Fortress/Concordia. I believe it is 2.0x but the "About" thing in Libronix didn't reveal the exact version. Everything seems to work great. When I'm reading text, about every third or fourth time I hit the "page down" button, there will be a pause before the text actually displays. This despite the fact that I copied the resources to the hard drive.
One caveat: Attempting to update the installation through the updater still messes everything up.
