Problem with CFileDialog !

Hi MFC-folks !

Envi : Windows NT 4.0 beta, MSVC 4.1, MFC 4.1 

I got a little problem with the CFileDialog. After closing it with "Open", a
ASSERT apperars in a mfc-source file:

DLGFILE.CPP:

int CFileDialog::DoModal()
{
[snipsnip]

	_AFX_THREAD_STATE* pThreadState = AfxGetThreadState();
	ASSERT(pThreadState->m_pAlternateWndInit == NULL);

	if (m_ofn.Flags & OFN_EXPLORER)
		pThreadState->m_pAlternateWndInit = this;
	else
		AfxHookWindowCreate(this);
[snipsnip]

	if (nResult)
		ASSERT(pThreadState->m_pAlternateWndInit == NULL); // THIS FAILS
	pThreadState->m_pAlternateWndInit = NULL;

[snipsnip]
}

Like you can see in the source file, the 'pThreadState->m_pAlternateWndInit'
member is set to 'this' and later checked for NULL (but only, if you press the
open button). 

My question is, what shall I do to avoid this assert or is it a simple MFC bug ?

PS: It fails under Windows 95 too !

Try removing the OFN_EXPLORER style.
