Actually, you have set DrawingArea.Cached to FALSE, so your drawing code must 
be put in the 'Draw' event handler. Otherwise, the behaviour is hard to 
predict.

You should not rely on the background and foreground property to draw inside 
the DrawingArea. Set them with Draw.Foreground and Draw.Background directly.

But I admit this is logical, so in the future, the Background and Foreground 
DrawingArea properties may be automatically transmitted to the Draw class.

Last, you should not use the Clear method when Cached is set to FALSE. It does 
nothing!

OK, this bug will be fixed in the next version.
