If you have specific issues that you’d like to call to our attention, post them and we’ll try to get them fixed up for the next version of LayOut.
Otherwise, you can go from 2017 back to 2016. In LayOut 2017, open your file, then do “Save As” and choose the “LayOut 2016” file format. You may lose some data in the down-saved file - for example, I believe that Table entities will become just text boxes and lines.
