Hello.
I have NChartControl and access to it from different threads. I noticed that if I access to chart control from any worker thread during it's repainting in main thread the repainting is too long (over one minute) whereas repainting without other thread's intervention lasts less than one second. By the way the application hangs in this minute. And I get a message from MS Visual Studio "ContextSwitchDeadlock Was Detected". If I break all processes I see that the main thread is in NChartControl.OnPaint() method and the worker thread is waiting for NChartControl.Document.Lock(). Why the other thread delays repainting? How to avoid it?
