Thanks to Larry of Flowerworks in beautiful Lincoln, Nebraska for discovering this bug
A bug was recently introduced with the 2015 version of flowerSoft that affects the discount option in flowerSoft.
The bug does not let you get out of the discount screen (if you are applying one) unless you hit the <Esc> key.
The bug has been fixed and will be uploaded into your system as soon as possible.
Here is the link to the original post.
