I'm using Chrome (latest version) on Mac 10.9.1 and repeatedly have an issue.
Normally I'm on the new posts page. If I get a PM I will go to that page. If it's a message that I respond to after I hit the send button if I use the back button on Chrome to thry and return to new posts a dialog box opens asking me if I want to navigate away from this page. At that point everything is hung. I have to force quit Chrome to recover.
