-Under Mozilla 1.7, VideoLink sets the assumed screen resolution to
-40 dpi, which I reckon to be the average resolution of a standard
-definition TV display.  This should mean that text with a font size
-expressed in millimetres or points will appear around the specified
-size.  Unfortunately this setting has a different effect under
-Mozilla/XULRunner 1.8:

-From version 0.10, until I have a proper solution, VideoLink will not

+VideoLink should set the assumed screen resolution to 40 dpi, which I
+reckon to be the average resolution of a standard definition TV
+display.  This would mean that text with a font size expressed in
+millimetres or points will appear around the specified size.
+Earlier versions of VideoLink did this when built to use Mozilla 1.7.
+Unfortunately the resolution setting in Mozilla 1.8 actually affects
+measurements in pixels and not measurements in millimetres or points!
+The assumed screen resolution is always 96 dpi.
+
+Please specify measurements such as font sizes in pixels because
+measurements in millimetres or points are liable to change if and when
+I can override the assumed screen resolution again.
