Backtest: Critical runtime error 512

[0xA0B1 FX5]

Hello,

when backtesting "Open prices only" or "1 Minute OHLC" I get lots of these errors:

pass 123 tested with error "critical runtime error 512 in OnTick function (sleep function reaches end of test)"

Using "Every Tick" works just fine, just is quite slow, thus I wanted to test M1 backtest to speed up testing.
