two questions

one...nautilus won't allow me to browse outside of my home directory
when im not root. when im root it works. It looks like i don't have
the right permissions for something, but i don't know where to start.
Can someone point me in the right direction??

two...has anyone else had any problems with Redhat 7.2 freezing? I've
installed it on my laptop and my desktop and its done it on both.
Mostly when the screensaver is running, but sometime not. Just wondering.

thx
