Since I used the Chinese to type, this problem has been occurred numerous times. Some times the whole article was gone(today it has been occurred twice, the title and two lines of contents were vanished in all the sudden, although I have clicked the return narrow on the top bar.  If I  reedit at the posted article, it could be vanished in one second, too. Although when I click the return narrow again, the new contents still can not be retrieved, but at least the exsting part is able to. How to fix it, my dear friends?

Yahoo mail used has the same problem. But it has been fixed for long time, there is a "draft" box available to be automaticlly saved before the mail be sent. But I could not save it at WXC. 真是苦不堪言，欲哭无泪！又溺水了，快救我哟！
