I was working in the subtracting fractions module. I was having a bit of a struggle. about every 5th problem tho I would answer. I would get the answer correct. Then I would click for the next problem. The screen would turn blank (white) and it would repeat the problem I had just solved. And the same answer would work. Happened many times during this session.
