This is the solution if the problem is that you cannot see the Show View Options:
Some kind of application that you installed, even if you don't know it did it, changed a setting in the finder preference file.
The solution: Go to home/library/preferences and open com.apple.finder.plist, then scroll to the bottom of the file and you will see and option named: ViewOptions-inmutable, make sure the checkbox is not selected, or that the boolean value is the opposite of the one it has right now. So if it has TRUE change it to FALSE. Save the document and use the Command
OptionEscape combination to see the Force Quit Apps windows, select the finder and click the Relaunch button.
