Don't know if its the same problem but this can happen if there are two different texture maps that share the same base name. For example if there are two props c:\redball\red.obj + texture file c:\redball\ball.jpg and prop c:\greenball\green.obj + texture file c:\greenball\ball.jpg. Poser will pick one of the ball.jpg files and apply it to both props even though the texture files live in different directories. Clicking on the explorer file will show the correct file which can be confusing.
