I wondered if the two bolts where the hinge join the door allow any lateral movement. If so, that would allow the door to move in/out in relation to the front wing. The posts in this thread appear to show that there is some adjustment possible.
Sadly not, as others have found the top hinges have no adjustment, plus self centering bolts.
Looking for Do-it-yourself Door Alignment Information
The hinge itself actually needs to be slightly longer. Or the bolt holes wider to permit adjustment. I guess you could take the whole door off and file them out.
