Hi, the method I used to update the display was to delete the object and then re-create it with the updated text. I have a hunch that there might be a more efficient method (like using .getImage() and .clear() ). Anyway, any suggestions or comments welcome :)

You have to click 0 about five times for it to start adding zeros. I think it is to do with my MathContext (I need to show more precision, even though 111.0=111.00). My code is like this: mc=new MathContext(display.length());
