Windows deleting Viewer's temp files?
Background: I use Calibre and its viewer on a Windows tablet. Since I mostly use the device as a reader, that means the main program and viewer are running constantly.
Lately--i.e. in the week since I upgraded the tablet to the Windows 10 Fall Creators Update--I've been experiencing a problem where the viewer fails the first time it needs to move from one file within a book to the next.
Example: I'm partway through Chapter 5 when I turn it off. When I resume reading, everything is fine until it tries to go to Chapter 6. At that point, I get an error message about missing files. If I close the viewer and relaunch it from Calibre, everything is fine again--I can move on to Chapter 6--until the next time I leave the tablet idle for a while.
This doesn't happen every time, but enough to be annoying. And, for the record, the Disk Cleanup tool is set to NOT delete temporary files. I had the same configuration in the previous version of Windows and never saw this problem.
Has anyone else seen this, and better yet, figured out how to fix it?
