Title pretty much says it all ….

1) drag an image to uploader
2) start upload
3) preview shows dupe of image (ie; image inserted twice)
4) post (save), post shows same (duplicated image)

Theme is unified, minimalist overlay.

Wondering if this is a known issue, something silly that I’ve overlooked (more likely than I’d like to admit !) or… ???

Searched in every way I could think of for instances of this problem, with no luck.

Thanks in advance.
