Nick,
As Phil replied earlier - it seems the font maybe getting messed up. Could you
send me a code snippet or check the params of the current font if they are
reasonable. You may also change the point size etc, and see if they make a
difference. Try changing the clip regions if they have an effect. Are you using
JDK 1.2 or JDK 1.2.2 ?
