Thank you so much for your hard work and help on this. Given the caveat, I'm a bit nervous to try it.

I can't image why.....
I installed it, and so far, I've had no problems arising from it. Not sure why that should be, given the Zenwalk experience, but it doesn't seem to have caused problems so far.
Also there has arisen some new questions as to the procedure and modifications needed for getting event sounds working in xfce. It can be done, as Mandriva one 2010 xfce proves. That is my goal.
Interesting. I've seen the option in the Zenwalk build of Xfce, but it doesn't do anything for me there at least. Not tried Madrivia in a long time. Good luck.
