I use Calibre and Calibre Viewer on my Microsoft Surface Pro 6. Before the last two updates to Calibre, I was able to leave the viewer application running in the background when I put my tablet in sleep mode and come back to the exact page where I left off in the viewer when waking it baking up. Since the updates, when I open my tablet, the viewer application has closed out and when reopening the ebook, it takes me back to the cover page. I haven't changed anything in the configurations of either the application or the tablet. Is there something I need to change or update in preferences to mitigate this?
