Russ, I didn't know you were looking into this issue.My thread of emails was with Rod.I don't see the thread represented in your post.
I type my many sources and citations in the "Person" pane in FTM2012 on the right hand side of the screen.They appear as long as I'm typing them.If I should "click" on the right hand side of the screen they disappear.Not always though.I can go up to the Green Bar on the right hand side of the screen, click on it, and then click on "indiv. facts" and they will reappear.(But not always).I was given a work-around by Rod where I can access the source citations in another place.Click on the "Person" tab while in the "People" workspace at the top left corner and you can see the source citations on the right side.You can edit, delete, etc. using this method.It's more time consuming but it does work.
In my case, when I know I have typed my sources and I can't see them in the person pane where they should appear, I run a Gen. Rpt. to see what's sitting there.I don't want to type duplications.
Yes, the issue is resolved with the work-around Rod provided me. It would be much simpler if I could "always" see the citations when I leave that person's screen and then have reason to go back to it later and it's not there.
It's impossible to copy/paste the problem.It's hard to believe other users of FTM2012 have not run into this problem.
