List boxes, in past releases, have always been defined with their height being in terms of number of lines, rather than number of rows in the form row + column layout values. The attempt has been made to preserve this as much as possible in 17.4. However, due to the preference to allow list, grid, and tree fields to expand whenever space is available to maximize the content they can display. If you have a list field that is longer, or shorter, than you want it to be, consider one of the following two solutions. 1. (Preferred) Specify a height of 0. If you are willing to do this, the list will size to fill the space to the next field below it, or to the bottom of the group box that the list is within, whichever comes first. 2. Adjust the height size in the LIST line for the list field to the point where it is the specific size that you desire it to be when your form is displayed.
