StateCharter Color Selection

Run StateCharter sample from GoDiagram Win 3.0.2 for .NET 3.5.
Click “Color” button and bring up the “Drawing Properties” dialog.
Click any color (from Pen or Brush or Text) and launch the color selection control.

Result: the color selection control is behind the “Drawing Properties” dialog.

Question: How could the color selection control be on top of “Drawing Properties” dialog?

Looked at the DrawDialog properties. TopMode is set to “True”. This is the reason.
