brown-out problem

In my code I have the following

Code:

#include 18f2520
#fuses HS, PUT, NOWDT, PROTECT, BROWNOUT, BORV27

I check the configuration bits in MPLAB, and I get the following
BOREN - Brown-out Reset Enable Bits - Brown-out Reset disabled in Hardware and software
BORV - Brown-out Reset voltage bits - VBOR is set to 2.7 V nominal

How do I actually ENABLE brown-out feature?

I've also tried

Code:

#pragma config BOREN = ON

After I set the fuses and before I set the fuses, but it doesn't seem to be helping. Any ideas?

Probably, you have the Build Configuration set for "Debug" in the drop- down box on the menu bar in MPLAB. It disables Brownout when DEBUG is selected there. Change it back to RELEASE and it allows the Brownout fuse to be enabled.
