    I have the same problem that you do. Check my post #73 on the previous page. I couldn't get it to run unless I changed the fonts to the original ones that came with firmware 1.1.1.

    I cannot believe that people replace or remove fonts and then expect everything to work...
    Come visit AlohaSoft

    Well, given that the program crashed with "bus error" from modified fonts, it is very strange. You would expect the program to have corrupt display, etc., instead of outright crash, ESPECIALLY when the programmer has said that it crashed while loading fonts.

    Not at all strange.

    You code to load a system standard font and don't check to see if the font is created as an object - after all, it is part of every iPhone, right?

    Then you pass the empty (nil) object to other code that crashes when they try to use the missing font object.

    Just what you expect in an object-oriented prgoramming system that doesn't have runtime checks for nil in every function - which would vastly slow down execution.

    Something is terribly wrong with this app...uninstalled and did a fresh install to make sure (on a 1.1.4 iPhone)

    set it to algebraic mode, typed in
    "1.33 +/- +" and the display/register immediately changed the -1.33 to -0.67

    this doesn't work.

    I made sure all the registers were set to 0 to start with.
