Please see the question "Why Can't I Place a Fixed-Size FXCanvas inside 
an FXScrollwindow?" near the bottom of this page:

	http://www.fox-toolkit.net/cgi-bin/wiki.pl?FAQ

For your example program, I replaced these lines:

	@scroller = FXScrollArea.new(...)
	@canvas = FXCanvas.new( @scroller, nil, 0, LAYOUT_FILL_X|LAYOUT_FILL_Y 
)

with these:

	@scroller = FXScrollWindow.new( self, LAYOUT_FILL_X|LAYOUT_FILL_Y )
	canvasFrame = FXVerticalFrame.new( @scroller, 
LAYOUT_FILL_X|LAYOUT_FILL_Y )
	@canvas = FXCanvas.new( canvasFrame, nil, 0, 
LAYOUT_FIX_WIDTH|LAYOUT_FIX_HEIGHT, 0, 0, 600, 400 )

and I get what looks reasonable. It draws a pretty picture, anyways ;)

Hope this helps,
