several times per day my platform just stops loading data intermittently.  Sometimes for a minute, sometimes 5 minutes...sometimes it gets "some" of the data and one or two charts will load...sometimes no charts load...but very rarely anymore can I do an hour of reserarch without restarting the platform several times.  I am using firewall friendly ports, and turning off my Norton software does not seem to help.  Any thoughts on how this can be fixed?  

Thanks. -Bill
