My Dutch Star has two pocket doors too .
Back edge of the door has a Velcro pad to hold it open and I believe a previous owner installed a clear plastic strap with snaps that we use when in motion .
The " not moving " part of the problem may be like one of two problems I had .
#1 The mount screws for the top rail worked loose over time and jammed the top hanging rollers of the door, there are screws visible with the door open in the hall way but two more hidden back in the pocket .
I had to remove the door , by taking down the panel piece that covers the top rail on the bathroom side to access the hangers to remove the door , then rig up a 90 degree driver to remove the loose screws and install larger ones with glue on the threads.
If you can look into the cavity between the top of the door and the rail and perhaps see a loose screw jamming the hanging rollers , I can take and post pictures of what I had to do for the repair.
#2 The pocket door is an aluminum frame with wall paneling bonded to it.
The bonding on one side let go and the panel bowed out enough to bind in the pocket , I removed the door ( getting pretty good at it by this time
) glue and screw the panel back to the aluminum frame, about 40 small brass screws 20 each side, I predrilled the aluminum.
