thanks for your reply.
I was forced (also if now I will retain) to look for an independent solution to manage files. Opus has nothing to share with explorer.exe.
It is explorer to create problems, still now when I open views (as control panel) that are still opened in the native window. But, because in the current situation I do not make calls to explorer for control panel, than for quite limited cases, as the notebook went to a production level, the issue is impacting really less than before. Not because was really solved but because was avoided, turning around.
I supposed that Windows 7 makes many things different; the point is that was expected to do that things better, not worst, as explorer is proving.
