Windows narrator support?

Hello, just wondering if there are plans to make SL more accessible with Windows narrator? It's what our company offers and so far SL and even Rise don't perform well with it.
I've noticed also that we have one file that did perform well with reader. It was published for SCORM 1.2 HTML5 a year or so ago. If I republish in the latest SL it now fails to work with reader. So there seems to have been an update that has broken it? Strange...
