Thanks Klaus,
I have added that in but it doesn't seem to work for some reason, this is the code I have in my krpano.xml file, does it look correct? All I have done is added the architectural bit on the end.
<!-- view/fov settings -->
<view hlookat="0" vlookat="0" fovtype="VFOV" fov="90" fovmin="30" fovmax="150" limitview="auto" vlookatmin="-90" vlookatmax="+90" architectural="1.0" />
