So I tried to give a pos rep but the dialogue box was partially covered by the quick reply window. I probably should have taken a screen shot. I might add a screen shot in a minute. Anyway, I couldn't click the "add" or "deduct" button along with the comment window and the confirmation button.
I made a post below where I said "making space" and then tried again and I had room to give the rep. Then I deleted my post.
I'll see if I can recreate and get a screen shot.
Edited to add screen shot
