I shortly updated from Neos 2.3 to 4.1.
In the media browser I face a funny phenomenon.
The visible part of the first page is loaded well: all images and all PDFs have an icon and a thumbnail picture. When you scroll down (and on all following pages) the thumbnail for PDFs is not shown, but the circling “loading” icon.
This is not a matter of “wait a little bit”. They circle for ever.
You can still access those PDFs, however this is very irritating.
Any hint is welcome
