Hmm, writing articles and inserting games with annotations works perfectly fine for me.
What web browser are you on? Maybe that could be the root of the problem. I have always navigated Chess.com on Mozilla FireFox and I have never had a problem. Maybe you should try this browser.
It is called the immortal game.
This is what happened when I tried to create and submit an article...

I wanted to use the tool for inserting diagrams, problems, chess games; so as to illustrate a game mentioned in an article that I wanted to submit. Incredibally, after inserting the illustration about 15 minutes later, and subsequently reviewing my article, I found that a huge portion of the text was no longer there. In other words, the article was ruined, and I had wasted 15 minutes for nothing! Has this happened to other members?
