Unwanted change to capital letter

[Beyond X]

When I come to the end of a text line and move to the next line by hitting Enter and continue typing to the next line, something unwanted happens. That is, when I finish the first word (all small characters) and hit space to move to the second word, the first letter of the first word changes to the capital letter.
I checked all items in Tools/"Option" and "Customize" but still cannot suppress this automatic editing.
Please tell me how to do it.

I would post the link to this with images but this forum doesn't allow that for some silly reason.
