Hi Philippe,

The border is supposed to be solid at all times, which is
why there are no controls over its line style. Something has
gotten corrupted here. Could you please send me your 'startup.mar'?

Line 5 contains a number describing which markings are turned
on or off, but says nothing about their colors. A description of
this line, and of _some_ of the rest of the .mar format (it's not
at all complete), is at

http://www.projectpluto.com/mar_fmt.htm

Line 5 is documented, but this line:

34 colors2 aaaaaa 0000ff ffffff 4a0dd6 ...

is not. The 'colors' are described as six-digit hex values,
with red, green, and blue given two hex digits each. '0000ff'
causes the border to appear in red. A seventh digit may be used
to indicate a line style (and an eighth to indicate a line width).
So you can edit 'startup.mar' and change that second 'color2' item
to, say, 0000ff, and you'll have a simple solid line again.
But send me your current 'startup.mar' first, because I'm hoping
to find and fix the bug!
