I have word wrap turned on for my comments. If I paste text at the end of a comment that will exceed the rightmost column, the comment wraps as expected but the window scrolls as if the wrap didn't occur. So if the text line to be inserted is 100 characters, I end up looking at a blank window and then have to scroll back to the left to see my code again. I don't think scroll on paste should be enabled if word wrap is on.
