just purchased LR4 and PSE 10. Set up LR4 to use PSE 10 as the editor. I watched a Tim Gray video demonstrating this and followed the steps.
When I attempted to send photos over to PSE through LR nothing happened. Nothing.
My system is OS X 10.7.3

thx. I am using Photoshop Elements 10 for now, not Photoshop, part of the CS.
There was an update for this know problem: LR4.1 RC2 via http://labs.adobe.com
That did it for me. I also updated ACR for both LR 4 and PSE 10. I appreciate
