If you're seeing a Radiant Photo plugin window with Photoshop's tool bar / options bar or other UI elements on top of it, we've got an easy fix for you.
Simply run Photoshop inside its application frame. To do this, just go to Window > Application Frame in Photoshop.
You can also press the Tab key in Photoshop to quickly hide all of those panels if needed: click on a Photoshop window and press Tab, then click back to Radiant Photo.
