BringWindowToTop is hanging on vista..   

Hi

i have an application which shows dialogbox on top of all
application . I am using the following code sequence..


BOOL BringWindowOnTop(HWND hWnd)
{
#ifdef _VISTA
    // TODO:
    // following code for non vista is hanging in vista when used,
    // need to figure out the reason and fix it
    return TRUE;
#else
	HWND hwndForeground = GetForegroundWindow();

	// gets the current top most window on the screen.
	DWORD dwFGProcessId = 0;
	DWORD dwFGThreadId = GetWindowThreadProcessId(hwndForeground,
&dwFGProcessId);

	DWORD dwThisThreadId = GetCurrentThreadId();

	// attaches the current thread to window on top
	AttachThreadInput(dwThisThreadId, dwFGThreadId, TRUE);

	::ShowWindow(hWnd, SW_RESTORE);

	// Now the window on top is also in the set of windows we are
intersted,
	// so bring window on top will put us on top of all windows
	BringWindowToTop(hWnd);
	SetFocus(hWnd);

	// detach from the previously attached thread
	AttachThreadInput(dwThisThreadId, dwFGThreadId, FALSE);
	return 0;
#endif
}

This api is called from dialogbox in Oninitdialog method it works fine
on xp system but it hanges
on vista when ::ShowWindow(hWnd, SW_RESTORE); is called .


Here the forground window is windows explorer .
and current thread is a user mode application thread which is
different form windows explorer.

Can you please tell me how to fix this on vista ?

Thanks
