Thanks, Mouser. These tests were performed over several days, with far more than 10 mins between attempts, and many restarts on all 3 PC's where we were trying out Boomerang. So if 10 mins is the relevant increment, it doesn't seem as if google is blocking us. I will check "pause between calls" and see if that works. FYI, another kind of error: even when the "debug" window and the "save file to favorites" show some truncated translation activity, *no* text whatsoever appears in the "Translated text" box. Strange hu? Also, at some points, when say 3 languages have been checked, a translation is returned but only for the first of the languages. This is when the "show all steps" option is checked, and of course in the past this has shown all the steps the program travels in executing its multiple translations. Thanks again.
