- Version 1.0.3 - Fixes bugs in the keypad and display. Multi-key presses should now work. For example, the "ON" & "." sequence for changing the digit separators now works.

Also fixes the display of digit separators which was broken in the last version and slightly enlarged the valid "hit" area for keys.
