For the last day or so, when I accept a hit, the timer starts not at 0:00, but somewhere between 3:30 and 4:30. This means that mTurk treats a lot of hits as expired even before I can start them. Oddly, I can still see the hits in my "Hits Assigned To You" tab - so I can return them and avoid an abandonment. I've tried rebooting my computer, and even using a different machine, but no luck. Has anyone else seen this and/or do you have any suggestions for resolving the problem? Thanks, Lisa
