How do I see the contents of the file in fiddler?

Im trying to see the actual files that have been sniffed by fiddler. So开发者_运维技巧 I have a load of session and in them is for example some .js files. But when I click on the entry in fiddler I cannot seem to see the actual file. When I click 'textview' I just see a black green screen at the bottom right hand side of the GUI.

May be the text color is same as background color so you cannot see them.

Menu >> Tools >> Fiddler Options >> Appearance >> Set Readonly Color, then choose a white color.
