It is meant to be used somewhat differently.
You can put all your drawing commands in a

Draw.Begin(DrawingArea)...Draw.End group of code.

However, it is much more practical to use the drawing area's draw event
http://gambasdoc.org/help/comp/gb.qt/drawingarea/.draw

because it will also deal with needs to redraw that come from outside the application i.e.other applications' windows that were partially overlapping. Have a look at the "Analog Watch" example.

So your Draw event would look like this:

PUBLIC SUB dwgScrabble_Draw()	'don't use BEGIN and END, it is already done
	...
	...
END

Also, do not use WAIT statements in here if there is any slight chance 
that something elsewhere wanted to be drawn. I learned this the hard way 
:-D
