Widgets aren't working

Question

OK, ever since I updated to snow leopard my widgets won'd select. What I mean is that I can't go into my package tracker and add a new package or the weather app and click on the forecast button.

Answer 1

Mihalis, thank you so much! Wow, I am really impressed! It worked!
Below my signature is a rundown of what I did. I was scared to touch this, but the instructions in the application were very easy to follow (as Mac seems to be pretty good at).
Widgets are working!!!!!
Many thanks. You've saved me a lot of time, grief, and a trip to the Apple store!
My best to you,
Annette
Here's what I did:
Opened the Disk Utility application. First I cliked on "Verify." It gave me this:
Verify permissions for “Macintosh HD”
Determining correct file permissions.
Permissions differ on ./Library/Widgets, should be drwxr-xr-x , they are drwxrwxr-x
Group differs on ./private/etc/authorization, should be 80, group is 0
Permissions verification complete
The privileges have been verified or repaired on the selected volume
When I saw Widgets were one of only two items, I felt safe to click on "Repair." It gave me this:
Repairing permissions for “Macintosh HD”
