The reason Wine doesn't work, according to Redhat, is because the version of glibc installed with RH9 breaks it.
You could try upgrading glibc but I don't reccommend it, I tried it and I ended up having to go back to the older version.

wine was only one issue. the netscape and realplayer were the other 2. I tried the new version out of curiosity. I guess that the old saying " if it ain't broke, don't fix it" holds true. I'm sure that in the short future the wine and netscape issues will be addressed. Realplayer seems to lag badly. i did get the realplayer 9 to work in RH 9.0, but some of my audio archives didn't play on it.
btw I'm running kde 3.1.1 with the RH 8.0. Got the rpms from a link at kde.org
it took a while to remove the old kde and install the new one, but it was worth it. I'm most impressed with the kget d/l manager and like the kweather feature.

I could not get avifile to run under 9.0 either. But ain't many peoples who likes that player anyway . mplayer and xine runs smootly

if you're fine with rh8, don't go to rh9...i use it and LOVE It, but i started off with redhat 7.1....

I hated 8 and switched to 7.3 and tried 9 on my backup and it was wayyy better than 8 IMHO. I still use 7.3 on my main box though.

For some reason, with Redhat 9.0, it would be locked up and unresponsive to anything except the power switch when I would leave it on overnight, so I suspect that they may have a bug in one of the X programs.

I went back to Redhat 7.3 after 3 days.

Was the change to RH 9.0 an upgrade or a fresh install? It may not be the version. I ran into that last year. Luckyly I had a second machine and a kvm set to cross reference setting. The one that wouldn't shut down just needed the setting changed.

Is RH 9 a radical changes from RH 8 like Win Xp changed from Win 98?

no, javacvb, definitely not...they got their naming conventions screwed up. It should be called, IMHO 8.7 or whatever
