Please manually create the ".corzoogles" file, and make it world-writeable, or else allow (temporary) write access to the directory that I live in, so I can create the file myself.
You can give the folder write-access in a shell/terminal (as root)..
chmod 777 /path/to/folder
or from your desktop, using the properties or "get info" for that folder, or with any decent text editor, save a blank ".corzoogles" file next to "corzoogle.php"
You could do the whole lot in a shell, too (as root)..
chmod 777 /path/to/folder/.corzoogles
Alternatively, switch off recent searches in the preferences!
