I took trunk-09012013.tar.bz2 from today.

Under these, the lines in TosWin2 are staggered (as Vincent
mentioned in earlier mail thread).  With 1-17-0 release kernel,
the lines worked fine in TosWin2.  My TosWin2 version is the one
coming with 1-17-0 MiNT release.

The TosWin2 version coming with the trunk package just crashes on
startup, to NULL pointer access.  This happens both with your and
the trunk version of mintara.prg MiNT kernel.

The issue happens also in the current build.
