Texture rotate automatically problem

when we paste texture to solids, some of pictures will rotate 90 degrees automatically even if the solids are totally same.
for example, 5 same size solid elements is placed in a line, only one of texture will rotate 90 degrees after pasted texture.
1. why the texture rotated even if the solids seems same?
2. since we don't know if the texture will rotate or not before paste, is there any method to avoid this before paste texture?
this problem occurred on all version of MicroStation 2004 Edition, XM and V8i.
