I have two resources open side-by-side: NA27 w/ GRAMCORD and BDAG. When I double-click on a Greek word in NA27, L4 automatically takes me to the corresponding word in BDAG. Wonderful! The little window at the top of BDAG displays the Greek word by default, but I can change this to show the page number instead. As I footnote my work, this display is very helpful. So I change it and now "Page 505" is showing:

Life is good. So I go back to NA27, find another word, double-click it, BDAG automatically shifts to the new word, but this little window has reset itself. Now it's displaying the Greek word again instead of the page number. Not good.
How can I persuade L4 to remember my choice? TIA.
