I'm using Safari. Last night I emptied my cache, but no change. The second time I tried, it worked, I did a trial run through the progress test with a mix of right and wrong answers (for once deliberate not my chinese!) and was directed to a lesson. I then repeated the progress test, only to be back to nothing working- this time again, after the first question. To be more precise, the background of the site loads fine, just not the questions and answers, and when I reload the page (if this is one of the times I get to a second question) it seems to wipe out the first question I answered (so no green and red bars across the top.) I only discovered this site a few days ago (sure you can tell that from my a/c!) but there was no problem with the test initially at all, and was one of the things I found really useful in directing me to material I'd find helpful.

Thanks!
