Hi Simon,

the reason for this behaviour is the CSS property "MozUserSelect" which 
is set by several widgets (including the table, exactly the default 
headerRenderer class) to "none". It seems, that Gecko is setting the 
property at the body element (-> "-moz-user-select:none") and this 
prevents any selection on the whole page.
Unfortunately you cannot set this property on element level to enable 
user selection on specific elements and leaving all other elements 
untouched, because this is still a bug in the gecko engine.

So the only possible workaround could be to manually set the property at 
the body element after the page finished loading. I've just experimented 
with it using the Firebug extension (this way you can enable/disable CSS 
properties on the fly) and if you dynamically remove the CSS property at 
the body element the text inside the HtmlEmbeds are selectable.

Hope this helps,
   Alex
