[CLUE-Tech] Can't mount cds

[Don Collier]

That it.  Thanks a bunch.

I do appreciate your help with RH 9, but it was not a very big deal to me.
 The only major differences that I could see, besides not being able to
dock, was that I got better resolution and color depth with RH 9. 
Everything else seems the same.

Thanks a bunch.
