I don't think it works. I'm extending the two theme. Before making any keyboard click changes, I get a click for the very first keystroke, then nothing else for the rest of the game. I thought this was a bug. After making the suggested changes, I get silence. (At least it got rid of that annoying initial key click.)
Booted up IE and couldn't get Adventuron classroom3 working at all. At first, I couldn't even get to the web site and discovered that I had to enable an earlier version of SSL & two later version of TTL in the options. Now I can't get past the loading screen after clicking the licence acceptance button. Any idea why that would be?
