When you draw a string containing 2 spaces like "this is me" then in the actual drawing 3 spaces are used. This prohibits exact placing of various sequential strings. The code below contains the fixes marked with "JV-2008-8-11"

Code:
void CreateLayout()
{
  double rectWidth = this.layoutRectangle.width;
  double rectHeight = this.layoutRectangle.height - this.cyAscent - this.cyDescent;
  int firstIndex = 0;
  double x = 0, y = 0;
  int count = this.blocks.Count;
  for (int idx = 0; idx < count; idx++)
  {
    Block block = (Block)this.blocks[idx];
    if (block.Type == BlockType.LineBreak)
    {
      if (Alignment == XParagraphAlignment.Justify)
        ((Block)this.blocks[firstIndex]).Alignment = XParagraphAlignment.Left;
      AlignLine(firstIndex, idx - 1, rectWidth);
      firstIndex = idx + 1;
      x = 0;
      y += this.lineSpace;
    }
    else
    {
        double width =  block.Width; //JV-2008-08-11
      if ((x + width <= rectWidth || x == 0) && block.Type != BlockType.LineBreak)
      {
        block.Location = new XPoint(x, y);
          x += width + this.spaceWidth; // JV-2008-08-11
      }
      else
      {
        AlignLine(firstIndex, idx - 1, rectWidth);
        firstIndex = idx;
        y += this.lineSpace;
        if (y > rectHeight)
        {
          block.Stop = true;
          break;
        }
        block.Location = new XPoint(0, y);
        x = width;
      }
    }
  }
  if (firstIndex < count && this.Alignment != XParagraphAlignment.Justify)
    AlignLine(firstIndex, count - 1, rectWidth);
}

Hi!

Thanks for the feedback.

At the end, you also have to add the width of a space:
Code:
        block.Location = new XPoint(0, y);
        x = width;


The next version of PDFsharp will do it your way.
