Joe,
That's the way it's supposed to be. The ClientRectange's Width/Height is
equal to the actual width/height of the control. You have to take an account
for the width of the line itself (1 pixel). It means that the right /bottom
lines of the rectangle will be drawn past the boundaries of a control.
