Fedora Users — nautilus & sound in FC2

I have scrounged around a bit in the archives but don't see any hits on this but I am sure there must be a solution. I have moved two machines to FC2, one (an IBM PC300PL) was an upgrade from FC1 and the other (an old Aptiva) I formatted the disk and did a clean install. I have similar problems on both in that the file explorer tool (is that Nautilus?) is acting like an old Window 95 tool such that it lacks the tree on the left of the window and opens a new window with each directory you open. I don't see any setting in it to change this and make the operation like it was in FC1. What am I overlooking?

My second questions is why does sound no longer seem to work. On both machines now (where sound was working in FC1 with no help just fine) the soundcard detection tool reports none found.

Any thoughts on either of these anomalies? If I didn't know better I would have thought that FC2 was previous version of FC1...
