So, as i said earlier, I started closing out the lesson every time I took a break and I saw my times drop drastically. Actually more than was to be expected. So i’ve been watching it closely, and it is not accruing any “study time” while I am in the sentence mode, which is where I’ve been spending quite a bit of time. So for a couple of days it’s giving me 7 or 8 hours of study time. And now it’s not counting time spent studying in sentence mode. Don’t know if this is going on with all users, or if it’s just me. I do have a Linux o/s on this desktop so maybe it’s got something to do with that? Anyway, I suppose I should try to figure out how to report a bug…
