Version 25.8.3.2 of Base.
When trying to change the border of a field of a form (format: list of values), from ‘3D’ to flat’, once I select ‘Flat’, the applicaton freezes and I have to close and restore it. It happens very often, but not always: sometimes, rarely, it works, but the colors of border and background disappear. If I select ‘Predefined’ it doesn’t work: I have to firstly select a whatever color, then ‘Predefined’ to get it set up. Very annoying.
Which system do you use?
And when using Linux: Do you use the LO packages of the distribution or the packages of LibreOffice?
