I don't think that the randomizer works correctly in the Question bank. I set up a test example, StratQbank. It seems to work well in that I can select any number in a subset of questions from the bank. I love this idea. But when I play the widget, it always seems to select the same subset. I had hoped that these would randomize again when you click the Retry button - they don't. But I seem to get the same set each time I try, even when I relaunch the widget. Do you need to have a fresh new browser session for the randomizer to kick in? I hope not.
