Exploded view, no exploded configuration!

I have a drawing view that is displaying an assembly in anexploded state. The drawing works fine, rebuilds well and is fullyresolved. I need to modify the explode steps to add a component tothe assembly so I opened up the assembly. It rebuilt and resolvedfine.

I went to find the configuration with the explode steps in it andimagine my surprise when I find out there is no configuration withan explode configuration in it! If I go back to the drawing andcheck the properties on the drawing view, the check box option for'Show in Exploded State' is checked and grayed out. If I change theconfiguration of the view, the explode collapses and I cannot getit back.

Has anyone heard of this problem happening before? The drawing wasoriginally created in SWX2007 and we have recently switched toSWX2008. Any known problems there?

Thanks for any help!
