I bring up the Bible Browser tool - I go to people, and select Jacob (son of Isaac) in NIV - I think it was 198 results. Then, I change the Bible to ESV - the filter selection still shows in the right hand panel, yet no results show (and there are 188 in ESV). I have to click start and begin again, to see correct results. I could see if a choice was selected that was not in the new bible selected (however in that case, the filter selections should be cleared and go back to Start, not leave the right panel in an indeterminate state with valid filters selected but no results), but in this case NIV and ESV had the same person as a filter - why should I have to begin again if I just wanted to move to another bible?
