Well this morning I'm not so sure. I got woken up about 4:30 by the cat, so let him out, then I HAD to pee, there was no way I would've got back to sleep. So I wee'd in my little pot. Then did another sd at about 6:30 when I got up. Thought there was something but then not so sure. The position of the control line is further over in its window so think the test line would be quite close to the middle frame part. Not sure I like the 2 windows as it's harder to see what's a shadow or not
