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. (:
