This was a post made yesrerday about a Safari crash:
https://www.chess.com/forum/view/help-support/new-game-crashes-safari-tab
I am using the Italian version of the site. Since the interface was upgraded a few days ago, I cannot access anymore "Game Analysis" (in Italian, "Revisione Partita") after playing a game. I am using Mac Os and Safari as the browser.
Thanks for any help.
