Win 10 DxPL6.0.1 Can't handle large directories - thumbnail refresh fails

Repeat of the tests with renamed image files (for better navigation of test images):-

@DxO_Support-Team I renamed the two bulk test groups as “BULK-xxxxx” and “Bulkxxxxx” so that I could show at what point things went wrong.

Cleared the PL6 database and re-discovered the “BULK” images and scrolled down the thumbnails in step with PL6 until

After discovery was completed scrolling down from the start of the thumbnails the problems start at the same point as previously identified

Navigating away and back changes nothing and it will require a program restart to change things (and, sadly, not necessarily for the better)!

Once discovery is complete.

PL5 shows none of these problems, in fact it was still running with the directory in focus during the name changes etc. and works just fine.
