I tried out WebJCS recently and I must say, I'm very much impressed with the program! I'm hoping to use it for a small collaboration project, but we're having some technical difficulties getting it to work properly...

WebJCS won't let us save levels. When we try, it just endlessly hangs on "Saving level...". It doesn't matter whether collaboration mode is enabled. We're both on Windows 7 using the latest version of Chrome. What are we doing wrong? Is anyone having the same issues?
