as has happened many times before, the video in the browser just stops playing and jumps to the next lesson. sometimes i can go back and get it to carry on, but sometimes i have to use the downloaded video (thank goodness you have this feature!). perhaps it is only my system, but i thought you should be alerted.
also this input window sometimes doesn't allow spaces to be typed. again, it may be just my system.
best wishes,
