// 2. the user refreshs a node that s a parent to the object
// which has the property page open. this will delete the
// scope object associated with this object, and will
// orphan the object.
// at this time, the cleaning of the scope object, will
// call release on the object once, but of course since
// we addref/release in the createproperty sheet stuff
// we are still protected from the object getting deleted
// from under us, thus we are at Refcount=1 or something like
// but with no scope/result object in MMC
// 3. now when the user clicks OK and saves changes to this
// orphaned property sheet and passes IT's handle allong
// with the change notification....
// 4. What happens next is -- since there is no MMC scope/result
// item -- thus there is only 1 refcount on the object.
// so when the user clicks OK -- really the object will
// Get DELETED... And this pNode that we are sending below
// will try to get dereferenced by the MMC.
// 5. the MMC will get the notification and get the pointer
// and try to call some refresh or something within the object
// itself.
//
// THUS THIS IS THE PROBLEM WITH SENDING pNode.
//
// To remedy this, what we'll do is:
// 1. when a property sheet is about to get orphaned
// we will set it's m_hScopeItem = 0 (gee since it won't have
// a scope/result item anywas).
// 2. thus if we see that here... that means the object
// doesn't have a mmc type scope/result object and we
// should not send the notification
