This will happen if you first size the component and then add() it to the
container. If you add the component first and then size it, it works fine.
Also, setting the layout to null appears to work correctly now, so that
you no longer need to create an empty layout subclass to do absolute
positioning.
Try something like:
setLayout(null);
TestCanvas theCanvas = new TestCanvas();
add(theCanvas);
theCanvas.reshape(10, 20, 100, 50);
Where TestCanvas is a Canvas subclass. The canvas should be positioned and
sized correctly.
