Bridge 13.0.2.636 - scrolling failure thumb view - german "Miniaturen".

If mouse pointer is located over the quickview - don't know english name - (in german its called Metadaten beim Drüberfahren anzeigen) the scrolling through thumbview is blocked.
It worked in the older version.
If the quickview is turned off, scrolling works, but unfortunately no quickview anymore.
Therefore bridge is unusable for me if turned on.
