I recently drafted what I considered a witty reply to a message to this forum, and made use of the "preview" button to sit back and enjoy my literary effort, before sharing it with the rest of the forum.
Satisfied with my efforts, I then sought to return to the earlier page - where I had drafted my reply - only to be told that the "page had expired" and I had to start again....
I this a NWC problem, or something I was doing wrong?
Usually, this is the kind of message you get when you press the Back button in your browser. After you are satisfied with the Preview, you then should press the form's Submit button, not the Browser's Back button.
Thank you for the advice. Of course, I now see that, had I, when looking at the preview window, bothered to maximise the screen and/or scrolled to the bottom of the page, I would have seen for myself how to use it properly!!
