Free42 v1.4.62 is released.Free42 is a complete re-implementation of the HP-42S scientific programmable RPN calculator,was made from 1988 until 1995 by Hewlett-Packard and the HP-82240 printer. Free42 was written from scratch, without using any HP code. You do not need any ROM images in order to use it, yet it is fully HP-42S compatible.

Free42 v1.4.62 Changelog:
* Windows version: now has an option in the Preferences screen to map the
Calculator key, found on many newer keyboards, to launch Free42.
* iPhone version: the hostname lookup for the HTTP Server window is now done in
a background thread, so that a slow or malfunctioning DNS server no longer
causes the app to freeze on startup.
* When EDITN was active, you could overwrite the edited matrix with a scalar
using STO, or delete it using CLV -- and then you would be stuck in the
Matrix Editor, and even CLALL couldn´t get you out. Fixed; you will now get
the Restricted Operation message when you try to change or delete the active
matrix behind EDITN´s back.
