Section View Problem

I have a drawing with three sheets; one for eachconfiguration of an assembly. I installed a new component into myassembly, and the component was part of all three configurations.When I closed the assembly and went back to the drawing, one of thesheets would no longer perform the section cut through the assemblyand told me that it needed to turned into a partial section. Itried deleting and redoing the section, but the problem remained. Ialso tried reinstalling the part, and deleting and re-creating thesheet within the drawing. When I opened a new drawing and startedfrom scratch, it finally worked. However, I would like to be ableto keep all three sheets in the same drawing file.

So, my question: Is this a problem anyone else has dealt with? Italked to my VAR tech support, but they hadn't seen it and justpushed the problem along to corporate. Is this problem unique to2009, because I never had it with 2007 (I skipped 2008).
