Found the solution. Still don't know why the problem arose, but I now
know how to avoid it: close xv between screen captures.
Actually found a much better solution this morning while rummaging around
in ImgagMagick. By using the import function with the -frame option captures
the window (and its frame) in which the '+' cursor is placed. The syntax is:
import -frame <filename>.<png|jpg|...>
I kept a small console window open next to the application frame and went
from one notebook tab to the next using import. When inserted in the LyX
document they all allowed changes to the bounding box.
