When I start the application, it is always shown as custom. I change later to A4, but when I close and open again, it's custom. I do not know where it stores this setting. I assume it takes it from the scanner, but I am not aware of such option there.

Git commit 26016dba7ba14f336feb2975ffc26c82457c485f by Nicola Felice. Committed on 28/12/2025 at 21:30. Pushed by sars into branch 'master'. Fix unselectable A4 page size Problem: observed on a Brother MFC-L3770CDW using the program Skanpage. When setting A4 as page size, the combobox switches automatically to the "Custom" value. Solution: I do not understand the exact purpose of the code but the logic of the original code looked wrong and this change fixed the problem on my system. My scanner for A4 has some wiggleRoom for the width and nothing for the height, switching the dimensions in the sum probably caused the problem. A scanner with different geometry will probably behave differently.
