wait, if you finish the emails, the whole screen turns black and thats it? or is this a glitch? (edit: nevermind, i just restarted the site. i guess it was a glitch.)
This happened for me too - seems like it happens when you scroll to the bottom of the inbox, I'm guessing it's caused by the coworkers clearing the mail down there, causing there to be nothing to display / scroll to, causing a crash.
