Save as Saves to Lightroom

Before, I could do a Command-E to open in Photoshop, do a Save As (to the Desktop, for instance) and it wouldn't get put into Lightroom. Now when doing a Save As from Photoshop, the edited file gets put back into Lightroom. What am I missing?

Lightroom 4.3, Photoshop 13.03, MacPro 2.8 Ghz, Snow, 18 gb RAM
