When using the edit program on pocket computers, line numbers will not show up properly due to the "Press Ctrl to access menu" text covering them up. My suggestion to fix this is to not write "Press " on pockets. (or something of that nature)

if not pocket then
term.write("Press ")
end
term.write("Ctrl to access menu")

Or maybe check how big the screen is, and from there cut out the 'Press'.

Fixed in next version
