When you run a replay with multiple charts, you are prompted for a "Processing Time in Seconds". This is the amount of data that will be processed in a batch. Therefore, depending on what this is set to and the "Replay Speed", your charts will stop updating during that time while the replay is running.

But, you should be able to interact with the program. Are you actually not able to interact with the system while this is occurring?

Also, we want to ensure that we understand how you are running the backtest. Please let us know if you are selecting one of the options in the "Trade" menu, or if you are doing this all from the Replay Control Panel window.
