Why no timberlist??

Suddenly there is no timberlist to be inserted on the drawing. This happens for interior walls where I have chosen to get layer 0, 1 & 2 as 3 seperate images. For wall 25, t.ex. there are following images: GF 2 Wall 25 (empty), GF 2 Wall 25_0, GF 2 Wall 25_1 & GF 2 Wall 25_2.

When I took out the drawings from Dietrischs I choose the option wall selection to be able to select only interior walls. What can have happened!!??

Well - I get a timberlist if a make images for all stories. But now I have images, that are not necessary, and that might make the function "Insert stored image very slow (see also other topic).
