Problem Receiving the first OSPF packet

I trying to send and receive OSPF packets. I am using RAW Sockets(socket(AF_INET, SOCK_RAW, IPPROTO_OSPF)) to do this.

I am successfully able to send an OSPF Hello packet however I am not able to receive a OSPF packet if I have not sent an OSPF packet earlier on the RAW SOCKET.
Scenario:

Working
Send_OSPF_packet()
Receive_OSPF_packet()

Not Working
Receive_OSPF_packet()

I see the receive packet using ethereal packet capture. However my application does not get the packet. I see that its got to do with kernal/os/lower layer (Not sure which one) not passing the packet to my RAW socket.

What do I have to do to Receive the First OSPF packet?

The Code written by me is in C language.
I use Winsock. The OS I use is Microsoft XP professional sp2

Please let me know of anymore details required.
