Not sure what happened, but now I cannot open my Applications folder via Finder.
A message pops up indicating:
There is no default application specified to open the document "Applications".
Permissions are ok:
drwxrwxr-x 76 root admin 2584 Oct 29 17:10 Applications
If I try to open the Applications folder from a command line, I get this:
% open /Applications/
2006-10-29 17:45:56.103 open[4229] LSOpenFromURLSpec() returned -10814 for application (null) urls file://localhost/Applications/.
I can access the folder via Finder if I cmd-click the folder and select "show package contents".
I tried to change the default Application to open "Applications" back to Finder, but there is no apparent way to do this from cmd-i.
