Event processing should be done frequently

After the click  'Compute portfolios' button,


1: I can't click any button. I can't click the 'Stop' button also.
2: Can't drag or resize the window. I can't control it at all.
3: Even though I successfully dragged the window, the view is not updated. Please see attached bitmap.


Request:
I want to drag/resize QuantAnalyzer.
I want to stop the task by clicking the 'Stop' button. This is very important. I have to KILL the QuantAnalyzer task by the task manager.


Note:
StrategyQuant uses CPU power up to 100%, but it never triggers such slow behavior.

I recommend you implement the 'Reserve 1 Core for UI, compute tasks in parallel on all remaining cores' function of StrategyQuant.
