Hello, I just installed Lion, and no i don't advice you to do it just yet any how, 1) in the finder windows i added a folder in the favorites in the sidebar, when I updated it its not working. It says shortcut error or something. No problem, I just want to delete it, but I can't delete it. I drag it out but nothing happens. I re-added the folder and it works, but the old one just won't go away...any fix for this? 2) I am trying to delete another user which is a guest user, i unlocked the lock in system preferences i clicked on the guest account but the (-) symbol sign didn't lit up, i can't hit it. What is wrong? any fix? any btw, does lion take any extra space for a side partition?
