Code Protection with PIC18F2525 problem

I can't seem to get the CCS compiler to set the code protection bits on the PIC18F2525. I have #FUSES CPB and #FUSES PROTECT=8 in my file. I thought those two would do the trick, but they don't seem to do anything. I don't know how to check this in the CCS program but have found the ID section in the MachX programmer that shows them to me. They are never set. I can manually set them in the MachX, but really would like the CCS compiler to program them properly.

The code is running fine, but I would like to understand the code protection fuses.
Any ideas would be appreciated.
(Note: I have also emailed CCS support just now and will update this message if they help out.).

You can see the fuse settings and the Config Word(s) at the bottom
of the .LST file, after you compile your program.

1. Post a small test program that shows the problem.
2. Post your compiler version.

Thanks for all the help. I didn't know I could see the programmed fuse settings in the .LST file. That is great. I haven't been looking at that file. I need to study the assembly code anyway to learn more about it. Gotten 'spoiled' by C.

Also, CCS support emailed me and discovered my error. I had a #device=ICD line in the file that I had forgotten about. Had it in there for testing. The code protection fuses will work if I comment out that one line.
