I'm using FlyGrid.Net Pro A customer reports the following exception...

Message: 'Object reference not set to an instance of an object'
Class: NineRays.Windows.Forms.Data.Rows
Method: [][](Boolean, Boolean)
StackTrace: at NineRays.Windows.Forms.Data.Rows.[][](Boolean, Boolean) at NineRays.Windows.Forms.Data.Rows.Reset() at ...
[] stands for a square sign which probably represents some characters that can not be displayed.

Is this issue already known? Is a solution available? Do you need more information for analysis?
