Hello Thomas.
First of all sorry for my late response, I’ve been off for a week.
I have checked and, yes, when I set IncrementalPreview to 1 the problem disappears.
I remember setting IncrementalPreview to 0 when I upgraded from version 10 to version 17 because of the issues I got, but my tests now (version 27) have gone well, so I’ll give it a try.
Thank you very much for your support.
