Cathy, I use Generations Grande Suite 8 on Windows XP.
I have the problem you described when I use the "Free Form Field," but clicking on the "Preview" tab before saving, solves the problem.
At the top of the source window there are three tabs: "Source Fields," "Free Form Field," and "Preview." These three tabs are there no matter which TYPE of source you use -- "Birth Certificate" "E-Mail Message" "Free Form" etc. Anything that you type in the "Free Form Field" will not be saved unless you preview it in the "Preview" window first, before hitting save.
I hope this works for you. If I have not explained it clearly, I will try again.
