Embedding Firefox 6.0.1: links not displayed correctly

Does the team have any ideas on this?

The browser displays pages correctly with the exception of <a 
href="..."></a> which are rendered as normal text. The link works when 
clicked and UpdateProgress and UpdateStatus on IBrowserFrameGlue all 
work as expected. What am I not handling?

Building as usual and embedding using XRE.

Thx++
