Some .scheme (TaharezLook.scheme for instance) contain an instruction to load a font (Commonwealth-10 font). Calling createFont() with that same font results in a "font already exists" exception. Added a call to isFontPresent() just before the call to createFont(). This is the preferred solution over the removal of createFont() since these are teaching samples.
