"Judy is my neighbor."
Well, it is supposed to be at the end but this is a common problem when typing Arabic in some platforms that do not correctly support the right-to-left system of writing.
You will see this problem prevail also when typing quotes (" ") and the exclamation mark (!) and few other symbols I guess. So, it's just a technical issue not a linguistic one.
Personally, sometimes I would type a letter (just anything) after the dot to bring the text back to the right alignment.
