The checkbox on delete history is not working

[wurzel]

Using 7.5.2 (maybe also on earlier versions) the checkbox to delete any entries of the history in a certain category is not working. f.e. having checked "Search: Subject", then closing the app and opening it again is not removing old search entries, they remain there until manually deleting them.

I haven't upgraded to the latest [abc] versions since there are no changelogs for the changes and I love to see what the update does before using it. If the current version (m?) is fixing this, I'll take the plunge

Thanks for your time!
