The problem is simple enough, just not (I believe) fixable in the program as it is. When you run an extracted data search (say as an example for monoclonal antibodies with dog studies with liver toxicities) you end up with a nice list of documents (mostly approval package reviews). You then click on a link you want to look at (Pharmacology review for one of the antibodies) and it opens up the PDF of that document. All well and good to that point, but now there is no way to navigate back to the document list (or I haven't figured it out). The best I can manage is to get back to the data search page where I then have to set up the same search all over again.

Workaround:

In order to get search result page user should do the following:

1. Perform Extracted data search
2. Get result page
3. Open PDF document
4. Push Back button twice (as a result user should see home page)
5. Push Forward button (once)

After that user will get search result page.
