I've been running BibleWorks 7 (7.0.012g to be specific) on Crossover 6.2 with a fair degree of success.
Installation was standard Windows-style install, no changes required. BibleWorks still has the famous problem of not displaying any of the buttons when run under Crossover, but since most (all?) of the functions are available via pull-down, this isn't a show stopper (though it is annoying).
Unfortunately, whenever you shut down the program (File -> Exit), you get the "BibleWorks has encountered a severe error and cannot continue" window. So the program works well for browsing through the Scripture and reading commentaries, but I don't seem to be able to save and reload any edited notes.
I haven't tested updating the software through Cx yet. More to come later.
