Hey ironandsteel. Thanks for the note here; that’s a really odd report, and I can’t say I’ve seen it before now. Is it possible this is something specific to the browser your client is using? It might be worthwhile having them test in a different browser, and of course to confirm that the issue persists even after deactivating other plugins or the theme (as it is possible there is a conflict on that front).
Let me know what you hear back there and we’ll do our best to help from there. A screenshot, if you can get one, would be equally valuable.
