Amaya 8.7 for Windows XP bug: incorrect CSS parsing

Hi,

Amaya 8.7 for Windows XP does not detect some errors in CSS files.

For example, Amaya finds no error in this css file:
  h1 { text-align: rightx; text-decoration: underlined; }
and renders it as the correct one:
  h1 { text-align: right; text-decoration: underline; }

Best regards,
Barto
