Cannot compile for 40MHz 4 x pll

Thank you!
I did what you suggested and using the following setting for the PIC 18F2320, my pbp program compiles!

@ __CONFIG _CONFIG1H, _HSPLL_OSC_1H

However, now my pic18f2320 resets continuously?
This is the first time I am using a pic18f.
Up to now I have been using a pic16f73 without any problems.
I have used the same circuit which worked fine for my pic16f73 (similar to the one on page 9 of the pbp manual, showing the basic setup).
Does anyone know of any specific issues that one should be aware of when changing from pic16f to a pic18f. Should my circuit be modified in any way? (both the pic16f73 and pic18f2320 is 28 pin pics with an almost identical pin layout)
Can it be that the pic 18f is more sensitive to voltage changes?
