Preparation of bars for backtest - should not freeze UI

[misova]

Everytime, when new backtest - with new bars (for example 1-tick range bars)
is started, Ninjatrader first prepares all the bars, before running backtest.

This completely freezes Ninjatrader and in case of big amount of tick-data,
this takes long long time.

Please improve this:
Preparation of bars should be done in separate thread, that does not block completely
the user interface.

Example:
I have imported tick-data for 10-year of EURUSD.
Then I started backtest with 1-tick range bars and NinjaTrader is completely frozen for
more than 20 minutes. I understand, that it is big amount of work, but this work is related just to the backtest, and should not block the user for 20 minutes with completely frozen user interface.

See how everything is frozen:
