Im getting an error screen when I try to access previous exercises. wonder is it linked in anyway?
Can you give me a screen shot of that please?
Well, that's not good. Let me try to reproduce it.
I can reproduce that as well. I've reported it so someone will get it sorted.
In the meantime, move from exercise to exercise with the Save & Submit button.
This seems to be working properly for me now -- could you try it again when you get a chance?
