It seems the Gallery is broken in 3.5beta3. (up to and including 22601 build).
When a post with a pre-existing gallery is opened to edit the gallery, the "Drop files anywhere to upload" message appears, then the gallery photo's appear.
BUT: the images shown are the images of this gallery and of a few other posts (while the post shows correct images in it's gallery before editing it).
Also, selecting an image to reorder it by dragging does not work.
both problems appear on Internet explorer 10 as well as firefox and safari, both on single site setup and multisite setup, so there's definitely something broken. (single-site is hosted at hosting company, multi-site at own server)
All was working properly up till beta 2.
(Yes, I've disabled all plugins, still nogo, so it's definitely not a plugin and starts immediately after updating to beta3).
Couldn't find a ticket in the trac system, so maybe someone who knows how to write a trac ticket can make one after confirming those issues?
with kind regards,
