Hi Khurram,
Problem #1 . I see that on interfaces with a priority set to 0. Set that inter
face to a priority other than 0. Then check the config it will show up.
Another thing is you frame-relay cloud fully-meshed of partial. If partial I se
t priority 0 on all spokes and on the hub router only I will invoke the neighbo
r command that will point to EACH spoke's interface. The neighbor command is no
t needed on the spokes. What you are essentially doing is telling the hub route
r to send the OSPF packets unicast instead of multicast.
Also when you are having adjacency problems at times : debug ip ospf adj and s
how ip ospf int is your friend.

I have HUB and Spoke Topology with default ospf network type (NON_BROADCAST).
R2 --- HUB (DR)
R5 --- Spoke (DRother)
R6 --- Spoke (DRother)
I am using ip ospf network non_broadcast (default type) on all routers
Problem # 1
***********
I tried to put "neighbor command" on my Spokes. Router accepts
it and then command vanishes from Configuration?? Any clue??

Why is the other spoke (r6) showing up here in R5 neighbor???
