Comments field no longer shown in Preview pane: v4.3.1 (Windows 10)

Since updating from Jabref v3 to v4.3.1 my Preview Pane no longer shows the Comment field. Previously it showed both the Abstract and the Comments fields. That was really useful since that showed what I thought of the selected article.
Is there a solution for that or do I simply have to go through the laborious process of appending all my Comments to the Abstract!
Since that update I also find I cannot change the font size of the preview panel which is tiny. All other font assignments work fine, as they did before.


I would suggest trying the current development version. It shows the comment field and the font of the PreviewPanel is also now better.
