I have Moderato version 3.5 build 1428.4. I just downloaded it about a week ago. The following behavior happens pretty consistently:

1. Start the server.
2. Load the Portfolio Demo. No alert appears. The page starts receiving real-time updates.
3. Submit an "order" for any quantity of any stock.
4. The alert appears, right after I submit the order.
5. Reload the page. This time the alert appears immediately after the data loads, as it should.

Thanks,
Jacob
