In order to *display* the zero-width rectangle, I have to add a (display-only) thin space, which does shift the rest of the text by a few pixels. We could make it customizable: either you see the zero-width rectangle and you live with the corresponding "display moves", or you don't see the zero-width rectangle. Of course, there might be other ways to represent the rectangle that don't suffer from this problem (e.g. only highlight the position of the mark, but not the line between the mark and point). If the display engine offered a way to overlay (rather than insert) glyphs/graphics, we would have more options. Stefan
