"please don't leave this page"-- getting this error message every 50-100 reviews and it never recovers. Pressing the "save reviews" button changes it to "saved" but it doesn't really save anything. This has been happening frequently over the past week and doesn't seem to matter where I am connecting to the Internet from. I am using Google Chrome on Win7. Anything I can do to avoid the problem? Thanks!

When you say that it doesn't matter from where you're connecting–are you in China, and you're trying from places in China? Or you're not in China? It sounds like an internet issue, so if you were in China, I'd suspect more headaches from the GFW.

Have a similar issue since a while. If I work down my daily queue and leave in-between and click the button (it shows "saved"), my first review items when restarting will be the last ten-ish vocabs. Also Win7 + Chrome.

I am based in the US, and I get the problem every 5 min or so, doesn't matter if I'm logging in from home, work, coffee shop, public library. Also tried skritter.cn and same thing happens.

Hmm. Do you have any problems like this if you're saving reviews using http://html5.skritter.com/ ?
