Door jump from room to room

[Top Spin]

I am working on a floor plan. I have created several rooms. Each of
them have one or more doors. When I try to align them, either by
dragging or nudging, the doors sometimes jump off of the moving room
onto the stationery room. I've tried making the room and the door a
group, but it still jumps.

Help!

Have you tried protecting the location attributes of the door?
