Hi,
The patch / OS/2 tools for Wordperfect 6.1 works fine on JFS or HPFS, the only issue is that it needs to use the 8.3 file names. Of course this is no different from any Win3.x application.
Otherwise I recently installed it on ArcaOS and had no difficulty.
I agree that the quick launch app isn't needed any more and I would not bother with it. Back in the day - when machines didn't have gigs of memory and it would take some time for Win3.1 apps to start up it was helpful. But today for most systems starting a Win3.x app is extremely quick, so there isn't really a benefit to running quicklaunch.
Otherwise I quite appreciate the efforts that Novel put into making sure that WordPerfect 6.1 ran well under OS/2 and had a few extra enhancements that were otherwise not available.
