Can't write code in FBrell code window

At fbrell.com I want to test some code and to see code of theirs existing examples. But, in none of the following browser IE8, FF3, Chrome I can't write anything in the text area. When I go to Save Code of an existing example there is for a second shown code of that example and after that it dissapears. Same thing happens at my home and my work PC. Googli开发者_运维问答ng about this problem wasn't successful. How to do it?

FBrell console is implemented in Facebook, JavaScript Test Console try it if it didn't work, try clearing the cache.
