I am having the same exact problem as this guy, http://codelaboratories.com/forums/viewthread/607/

I have the problem on 3 computers.  The only common theme is an AMD processor… can anyone confirm this or know why exactly?  Anyone at CL have this working with an AMD proc?

AMD x64 DESKTOP #1- DOESNT WORK
AMD x64 DESKTOP #2- DOESNT WORK
AMD x64 LAPTOP - DOESNT WORK

INTEL x64 DESKTOP - WORKS
INTEL x32 LAPTOP - WORKS

After some testing it looks to be an AMD processor issue for sure.  Perhaps only AMD x64, not sure since I don’t have an AMD x32.  All my development machines are AMD.
