Kenneth,
In debug mode the init function is being used.
In order to know whether mapguide server is requested I was seeing the HTML
firebug tab (see image attached) and it's possible see the image that
mapguide server has sent.
Zac,
There is nothing in the firebug console tab
maybe the image attached could be a clue what the viewer, in this case open
layers is failing.
Regards,
