Double clicking on attached forms submitted by e-mail

First, I used 'mailto:myself [at] email [dot] com' to distribute the form as 'PDF complete document'.

During the testing of a form that I created, the Help file said to "double click the attachment" which would "open in Acrobat" and the "form data could then be exported to a spreadsheet". That is not exact quotes but close to it. So, I e-mailed a completed one to myself, double clicked it and it opened in Acrobat. Above the returned form was a ribbon that gave me some options, one of which was 'Export', and below that was the data in a spreadsheet-like format, then the completed form. I clicked the Export button and exported to a .csv file. I was very impressed.

Now, the problem is that I have since gone through several drafts of the form, and have gone through this same test, but it no longer opens in Acrobat the same way. No more ribbon with option to Export, no more spreadsheet-like data below that. It just opens asking me to fill in the form. If I want to save the data, I have to go to the Forms menu and select Manage Form Data which only gives me the option of 'Merge data files into spreadsheet' or 'Export' which does not give me the option of saving to .csv.

The group I made this form for is small (about 35 people) and this distribution is great and would be very fast with this kind of data collection and exporting. I would like to get this data collection method back. What has happened and how can I get this back?
