Moved my mapping activity on the laptop for now. Odd and annoying problem: I can't select brushes\faces from up close. It's as if they have some kind of specific point where I can only select them, or from a great distance, but that is clearly not the solution.
I suspect it has something to do with the Intel Drivers perhaps? I have an Intel HD4000 graphics on my laptop and Nvidia 650m ( hl1 is forced to use HD4000, idk why, but it works fine anyway).
