I succesfuly upgraded (not freshly installed) 6.10 over 6.06 last week. Everything seemed fine as far as hard/software interaction but I have had 2 problems with specific programs

1)Nautilus appears to be completely broken as I get the error msg: “ The applicatio “nautilus” has quit unexpectedly” shortly after I try to start it.

2)Gnome menu bars will not properly change position. After before/during the update i decided to play around with the menus for something to do and got it stuck in the middle of the screen. Now, when I drag to try to move them they're stuck.

If anyone else has had these problems please let me know how you went about fixing them.
Otherwise, is there anything special I need to do in order to reinstall 6.06, or can I just put in the cd and restart?

thanks ahead of time

If you want to replace the upgraded dapper to edgy with dapper, you'll just need to reinstall on top. If you have a different home partition it'll be a quick move. You could also do this with Edgy and get a fresh install.

Had the same problem,
simple reinstall of Nautilus worked for me.
