I'm running Gentoo Linux with kernel 2.4.25, glibc 2.3.3, and have been using Crossover Office 1.3.5 for quite some time with sucess (running Quicken 99). I was even able to get BW4.0 running without a problem, but realized that the hand-me-down copy I got was unlicensed, so I bought BW6. Well, I haven't had as much success with BW6.0 -- whether with Crossover Office 1.3.5 or 3.0.1 (demo), I'm able to install DCOM/IE without a problem, and then install BW6 without a problem.
I'm even able to start up BW6 ok... but at some point during program execution, without any discernible pattern I've yet to discover, BW/wine will crash.

Before the crash, I've gotten as far as browsing verses, seeing word tips appear, etc. -- yet at some point, wine crashes, and the limited backtrace offered in the debug log is not terribly illuminating (there's a page fault on read access to 0x0 in 32-bit code). Changing the "Windows" setting for bw600.exe hasn't improved things at all.
I don't suppose anyone here has seen (or resolved) similar symptoms?
