I've used Logos with Crossover Office 2 and 3 and it works great. A little slow, but otherwise its wonderful. I installed Crossover Office 4 and as normal, deleted the entire .cxoffice tree and reinstalled everything from scratch. Logos installed without a problem and is faster than any previous version (especially running on KDE 3.3), however it has a problem where all the menus are totally illegible - in some weird hieroglyphics. Doesn't really matter, though, I never use the menus.
