It appears that WealthLab doesn't update the cosmetic chart until after the Strategy finishes running. Is there any chart equivalent to FlushDebug to force a Strategy to update the cosmetic chart while the strategy is running?
Concretely, I have a message box to confirm that the chart pattern is correct before continuing with the Strategy, and I can't see the chart pattern until after the message box closes.

This is by design. Certain cosmetic chart features etc. are disabled where they are not needed - like in multi-symbol backtests, Combination Strategies, and of course Strategy Monitor. You have to redesign your strategy to not use any input like message boxes in this context.
