I just got version 4 with the NASS. It worked for a while, but I lost both the top and bottom toolbars. I tried exiting and restarting the program several times, and also tried rebooting the phone. Still no toolbars.
To the best of my memory, the last place it worked was when I was in the GWHS. I think it was when I tried going back to the NASS that I lost the toolbars.
I had noticed that when I have the settings for Strongs set at "word" the GWHS doesn't have words underlined or Strong numbers. I like to use the NASS in the mode where it shows the underlined words, but the GWHS doesn't show the Strongs (or underlined words) that way. Since I don't recognize the Greek words I rely on the numbers when I use that version. That means that I need to change the settings to show the numbers any time I compare, and then swithch back to the word mode. I think each version that has strongs numbers should have a setting for which mode to use, or else the GWHS should show the numbers regardless of whether the settings are for number or word.
Anyway, I have no toolbars and don't know what to do besides deleting the program and try installing it again.
