Well, look what happened again right after I started this thread on my web page:
No, I did not abandon this game - the page was hijacked by an advertisement.

My dearest chess.com - why do you hijack the entire web page in the middle of a game? This makes no sense! Don't you want people to come to your website to play chess? This is ridiculous!
Please report ads like that if they happen.

I am not having any trouble with the website. There is a feature on a Mac to hide distracting items on the bar where you type in the address. 'box with 2 small lines under it.'
