Ghost auto spans regardless of non span option?

I am attempting to take a ghost image outside of altiris tasks, just using the ghost exe and choosing to take the image.

I have de-selected spanning and once it gets to 2GB it starts to span regardless of the setting.  In the past this has worked fine, but now it seems to not work as it is supposed to.  

any thoughts?

Ghost 64bit version 12.0.0.7276
