Stylesheets + J2sdk 1.4

Question

I have recently migrated my code from j2sdk 1.3.1_03 to j2sdk 1.4.1_02. I am using JavaHelp 1.1.3.
All my html pages where previously successfully imcluding a style sheet for displaying the help.
In 1.4.1_02 the style sheet is not being applied. I have tried putting the styles in the head section of the html pages directly, but they are still not applied.
If I put the styles directly against the html elements, they works.
Obviously this defeats the point of a nice centralized way of controlling the styles!
Does anyone know what has changed in 1.4.1 to break JavaHelp's use of stylesheets or do I just need to be using them differently?

Answer 1

To further qualify this, I just discovered that it is only applying the styles which are directly on elements e.g.
This works:
body
     background: #ffffff;
     color: #000000;
     font-family:Arial, Helvetica;
     font-size:12.0pt;
     font-weight:normal;
This does NOT work anymore:
p.SubHeading
{     font-family:Arial, Helvetica;
     font-size:14.0pt;
     font-weight:bold;
     margin-top:6.0pt;
     margin-right:0cm;
     margin-bottom:6.0pt;
     margin-left:0cm;
