Depending on the browser you use, you will experience the one or another
quirk in the terminal emulation. These web browsers are reported to run JS-Forth
(in order of terminal emulation usability):
Firefox, Mozilla, Netscape, Epiphany, Galeon : good
Opera,Safari,Konqueror : fair
Internet Explorer: poor
Input key handling is broken for Konqueror 3.3.1, possibly before. Konqueror 3.3.2
cursor positioning is not good, similar to Opera. Backspace doesn't work with
Internet Explorer, try ctrl-q instead. Error handling and key? are broken with Internet Explorer,

Best viewed with resolutions and font sizes which allow placement of the two input/output areas next to each other. Try reducing the font size if one is below the other (Firefox: ctrl-minus)
