I guess this is some kind of bug…

When I upload images via the uploader I get a thumbnail image og the uploaded image. That is fine. But if I edit the image and upload it again the image is still the old image – both as the thumbnail and the actual inserted image.

The medialibrary also shows the new (right) thumbnail but when editing I get the old (wrong) image.

The only way I can upload the new image is by giving it a new name…
