I do a search and get a list of topics that I need to work on. I select "edit and tag", do some edits and when I'm done click "Update and List Topics" to save my work.
Am returned to a set of search results that shows only the topic that I just edited. Clicking "Back to search" takes me to a new search form with the ID of the topic I was just editing entered it in.
At some point I expect to get returned to the same screen I was at before I started editing this topic - i.e. the search screen populated with my previous search (updated with the current data).
At the very least the "Back to search" button should do this instead of taking you to the search form that matches the topic that you just edited.
This is the expected behavior. To keep your search list, use the "in new window" options (which has just been fixed).
