For more than a month now, I have been having problems usually within a round or two of starting I get a "communication failed" message in the chat box and, now, never see any other players named in the "social" box. I also have fairly frequent crashes when I'm playing using either of the browsers I have (Safari and Firefox). It seems the Mojo system is acting weird all around...or is it just me?

P.S. - I have emailed the Grab support folks about this a couple of times and got no reply

Now I have got a reply. The word is that this problem of disconnections and crashes is being widely reported and that they are trying to fix things; let us hope!
