Hi

When you guys change the signature of a virtual, if we have overridden it, we don't get called any more.  So changing the signature introduces a heap of bugs for us.

In CXTPPropertyGridItem, the prototype for OnValueChanged went from void OnValueChanged(CString strValue) to void OnValueChanged(const CString& strValue).

Consequently any place where we over-rode custom property grid item objects for special cases, no longer work.

This is really really dangerous, and there should be a big warning somewhere about it.

The sort of bugs it creates are hard to find, and we don't expect to have to fully regression test everything on every CJ update.

C'mon guys help us out here.
