Photoshop :: Layer Selection Few Pixels Off

The issue:When I ctrl+alt+right-click to select a layer, I can click the actual layer, or about 6 to 10 pixels below the layer. This latter option (the 10 pixel margin thing) is rather annoying when there's a layer below it, that happens to stick out 10 pixels underneath that layer.
 
It basically requires me to set the higher layer to invisible, and then rightclick again.There's a slight difference between pixel layers and vector layers, as vector layers seem to have a bigger "hitbox" than pixel ones.
 
The most annoying instances are layers with, for example, a one pixel line. You pretty much have to *guess* where to click, as everything is so close to eachother.I work in webdesign, and am working with pixel-perfect designs all the time, so this is something I deal with on a daily (read: every few minutes) basis.
  
My version of Photoshop

- CS6, update it frequently on my home PC & Work PC
 
It's worth mentioning that I didn't have this issue before CS6, and have been using PS for about a decade, +- 30 to 50 hours a week!
 
Before you claim it's the computer, the systems I've noticed this on:

- My home PC (16gb ram, couple SSD's for scratch disks, GTX670, core7 etc)
- My work PC (16gb ram, no scratch disks or fancy gfx card, core7 as well)
- Girlfriend's MacBook pro
- Her Mountain Lion running desktop (custom build, hackintosh)
+ several other PC's at work (programmers running wildly different systems and OSes)
 
We have several Adobe subscriptions; I have one, my girlfriend has one and at work we have about 3 or 4.So, it's probably not the computers.
