Yes - one of my mails - but I'll save you the search. This is from
the View guide...
line-list: A BLOCK that is used to track the offsets of text lines
when text is being displayed. When more than 200 characters of text
are being displayed, this list should be set to NONE when large
changes are made to the text. This allows REBOL to recalculate the
locations of all TEXT lines.
So, adding...
testo/line-list: none
before show testo should fix the problem.
So, a bug Ryan? Hard to say, but it has the feel of a work-around of
a bug. (:
