A few days I complained the SA EHealth web site seemed to not be standards compliant.
Just looked at the update history of Firefox as it went from Version 17.0 to 17.0.1
Guess what - Version 17 messed up something in the rendering engine. It is now fixed.
The page found here now looks as it should and does in IE and Safari.

Sorry guys - Firefox goofed. Not you!
