If the cursor's in a text box and there is nothing in there, or if it's after the space after a period, I cannot make the damn thing do a lower case character, except by writing two of them, then cursoring back and deleting the caps

To reproduce:

Write this in a text, excluding the "" marks
"HELLO. "

that a period followed by a space at the end

Now how do you insert a lower case character? If you press w, it inserts W, it you tap shift, it still inserts W, if you hold shift.. it inserts W
