A very similar issue to the one mentioned in the sticky thread "NinjaTrader 7 - Zen-Fire Connection Issue" is occurring for me in beta 20, on XP Pro (32 bit).
Approximately 20% of the time when I start NT7 and connect to my data provider (Zen-Fire (Mirus)) I get a constant loop of connect, disconnect, connect, disconnect ... The only way out is to kill the ninjatrader.exe process and try again. Here is an example of the log when this is happening:
21/08/2010 12:09:17 Connection Mirus: Primary connection=Connected, Price feed=ConnectionLost 21/08/2010 12:09:15 Connection Mirus: Primary connection=ConnectionLost, Price feed=ConnectionLost 21/08/2010 12:09:15 Connection Mirus: Primary connection=ConnectionLost, Price feed=Connected 21/08/2010 12:07:36 Connection Mirus: Primary connection=Connected, Price feed=Connected 21/08/2010 12:07:35 Connection Mirus: Primary connection=Connected, Price feed=ConnectionLost 21/08/2010 12:07:34 Connection Mirus: Primary connection=ConnectionLost, Price feed=ConnectionLost 21/08/2010 12:07:34 Connection Mirus: Primary connection=ConnectionLost, Price feed=Connected 21/08/2010 12:05:54 Connection Mirus: Primary connection=Connected, Price feed=Connected 21/08/2010 12:05:53 Connection Mirus: Primary connection=Connected, Price feed=ConnectionLost 21/08/2010 12:05:51 Connection Mirus: Primary connection=ConnectionLost, Price feed=ConnectionLost 21/08/2010 12:05:51 Connection Mirus: Primary connection=ConnectionLost, Price feed=Connected 21/08/2010 12:05:51 Connection Time to flatten=00:00:00, Flatten all=Disabled 21/08/2010 12:04:11 Connection Mirus: Primary connection=Connected, Price feed=Connected 21/08/2010 12:03:57 Connection Connecting to NinjaTrader data server (64.202.118.179/31654) 21/08/2010 12:03:57 Connection Mirus: Primary connection=Connecting, Price feed=Connecting
Also (and this may not be a related issue, I'm not sure), even when the connect works as it should it seems to take a long time between the "3 note chime" and the connection box going green - on average, about a minute. During that time NT7 isn't responsive to mouse or keyboard inputs. On NT6.5 it takes about 10 seconds (however, my NT6.5 setup is on a different machine, not the same as the NT7 install so I cannot know whether the difference is due to the system, or due to the version of NT).
