Oh darn.  Well then, to answer your initial question, no you don't need
to put a header and so forth on your resource.  There are really any
number of things that could create this problem; most of them could be
eliminated by calling WriteResource directly after you call AddResource.

What seems most likely is that you're forgetting that the resource
handle becomes sacred after you pass it to AddResource.  That is, the
system handles it from that point.  If you call DisposeHandle or
otherwise overwrite it or mess with it in any way other than with
Resource Manager calls after that, you're asking for trouble.  Best to
add it and then have your software ignore the fact that it still
exists; let the system take care of it.
