Gradient Maps doesn't work properly when editing a photo from Lightroom

Question

When I open a file in photoshop to edit and apply a gradient map to the image, it works fine. However, when I open an image from Lightroom (right click image, EDIT IN Photoshop) and apply the exact same adjustment layer, NOTHING HAPPENS. It's the strangest thing and for the life of me, I can't figure out what I'm doing different! As far as I can tell, the only difference is that the image from Lightroom is in 16 bit ... but when I change it to 8, still nothing happens.
My process: I apply a pastel gradeient on top of the image (preset: brown, tan, beige) and choose the "Pin Light" blending mode. Normally (as in opening an image outside of Lightroom), this gives my picture the desired effect. But when I open the image from Lightroom and apply the exact same gradient map, nothing happens. If I shift the color within the selector in the map window, I can eventually get the gradient map to reveal itself and the picture to show different colors, but ONLY if I move the color selection to the more saturated end and away from where I actually need it to be.
My setup: I'm working on an iMac, OS X > Lightroom 5 > Photoshop CS5. I'm clicking on DNG pictures within Lightroom and then selecting EDIT IN Photoshop > then working within photoshop.
Any suggestions would greatly be appreciated! Thank you.

Why not keep things simple and create a shortcut on the user's machine that uses this target command:
\\SRV2\d$\dir1\subdir1\subdir2
Simply because dir and subdirs are no constants.
Just imagin you have a webpage that looks like this :
Proj. #   Custommer    directory                                                bunch-of-other-stuff
4538      Microsoft        \\SRV2\Big_contracts\US\2014\software   etc
4539      Nokia             \\SRV3\Prototypes\EU\2012\hardware      etc
4540      So-else          \\SRV3\Big_contracts\EU\2013\software    etc
Instead of the full path you have a small folder icon (to save space). And clicking on this icon will bring you directly to said path.
It was extremely convenient, very user-friendly. And it has been working for over a decade, and today my users are frowning...
I think you are pushing psexec.exe beyond its limits.
No, it's working perfectly on Win XP. I just find it too sad that it no longer works on Win 7. I view this as a regression.
 When you run it the way you do it you actually do open a further Explorer process but it remains invisible to you because it runs in the background.
No, the user does get a new explorer windows that pops to the foreground. The
only trouble is that it opens in "My Documents".
Of course I could (try and...) teach them to right-click, copy the link, paste it in an explorer and so on, but they are going to hate me.
Thank you
