I had the same problem @moshe experienced.  I didn't realize I had to check the box of the month I just entered, as opposed to last year when I checked the next box.  It was annoying to have to check 11 boxes when everything was the same.  Now, I can check it once and get it all done at once.  Seems like an enhancement.  Except when the amount changes during the year.  My personal preference is not to type over something that is already there.  So I can see both sides on this one.  Since in most instances there probably won't be change during the year, overall I would consider this a positive change.

Bottom line is no one is going to be happy with all changes/enhancements made.
