WebTest not appearing in Fiddler save menu

I am trying to save a fiddler output to a .webtest format. I used to select file/save as but now I cannot see the .webtest option. Could anyone tell me why this might have dissappeared from the Fiddl开发者_如何转开发er save menu?

Thanks.

I have version 2.3.0.5 of Fiddler and the .WebTest appears under File->Export Sessions->All Sessions/Selected Sessions->Drop down for Visual Studio WebTest
