Hello,
Latest NT8 build. Had this same error lots and lots over last few days, so can confirm it replicable and a repeating issue. Happened about 10 times to me so far today.
NT8 becomes unresponsive when then strategy analysis chart is visible after running a backtest and you enable or disable a strategy in the main command window, or start and stop the playback feed (or a bunch of other stuff). The whole platform is then unresponsive and occasionally, the chart window flashes.
Unfortunately, it never recovers, requiring you to 'end task' and start all over again. This only happens if the chart window of the strategy analysis is showing a chart of a back test. It does not happen (I think) on the summary page, for instance.
