This happens with both Doors & Windows & I find this odd & perhaps a Bug:
- Create any number of random Windows with different attributes
- Choose one at random
- Pick up this Window's attributes with the Eye dropper
- Select with the Magic Wand & select all the windows
- Apply the Eye dropper's attributes to the selected windows & they change
Follow the same as above, but with the windows inserted into a wall, or series of walls
- Only the one window that has been touched by the Eye dropper's bucket changes its attributes
