I have had some issues with the different versions of PBP so I upgraded to Vs PBPX 3.1.0.4

This program compiles just fine but it does not enter the interrupt on RX
Code:
    INCLUDE "modedefs.bas"
    include "ALLDIGITAL.pbp"
    INCLUDE "C:\PBP\DT_INTS-18.bas"     ; Base Interrupt System
    INCLUDE "C:\PBP\ReEnterPBP-18.bas"     ; Include if using PBP interrupts
       
    Define PULSIN_MAX 1000
    DEFINE HSER_RCSTA 90h   'Hser receive status init
    DEFINE HSER_TXSTA 24h   'Hser transmit status init
    DEFINE HSER_BAUD 9600  'Hser baud rate
    DEFINE HSER_SPBRG 25
    DEFINE HSER_CLROERR 1 
    DEFINE OSC 4
    OSCCON =$D2 'clock speed
     mem1 var byte  

ASM
INT_LIST  macro    ; IntSource,        Label,     Type, ResetFlag?
        INT_Handler    RX1_INT,    _read_serial,   PBP,  yes
        

   endm
    INT_CREATE             ; Creates the interrupt processor
ENDASM   

@  INT_ENABLE   RX1_INT     ; enable external (RX) interrupts 

   
 MAIN:
 
 SEROUT2 PORTB.0 ,16468,["here",cr,cr]

 pause 500
GOTO MAIN  
 
 read_serial:
 hserin 250 , NoRS232,[mem1,mem1]
 
 serout2 PORTB.0,16468,["got it",cr]
 Pause 1000

@ INT_RETURN 

NoRS232:

serout2 PORTB.0,16468,["No rs232",cr]

@  INT_RETURN
The exact same code runs in the 18F1320 except the OSCCON is $60 for the 18F1320 and $D2 for the 18F26K22.

Does anyone know where I might be needing to look?
