Accelerators in modeless _property sheet_

Environment: VC++ 4.2, WIN95

I have several modeless Property Sheet's in my application and I'd like
accelerator keys to function even when the sheets are active.

I've looked at KB article: Q117500
"Using Accelerators with an MFC Modeless Dialog Box"

Which explains that to get accelerators to work in a modeless dialog, just
override PreTranslateMessage to pass the key event to the mainframes
accel-table.

I tried a similar approach with the modeless property sheet overriding
pretranslate message on all the following:

the CMiniFrameWnd that holds the sheet
the CPropertySheet subclass
each CPropertyPage subclass

But none of these methods are called.

Spy++ verifies that the WM_KEYDOWN and WM_KEYUP messages that should issue
the accelerator are caught by the current focused control in the sheet, not
by the Frame, Sheet, or Pages.

Is there any way to get these messages before they are distributed to the
focused control? I'd hate to have to write special button, list, slider,
etc... subclasses just to trap this message!

Thanks for any help.

Jeff,

FWIW: I have the same problem in 1.52.  Here's what I put in my property
sheet class to get the mainframe menu accelerators to work (note:
accelerators on controls in the property sheet still do not work):

BOOL CMySheet::PreTranslateMessage(MSG* pMsg)
{
        HACCEL hAccel = ((CMainFrame*)AfxGetMainWnd())->GetAccelTable();
            
        if(hAccel && ::TranslateAccelerator(AfxGetMainWnd()->m_hWnd,
hAccel, pMsg))
     	      return TRUE;
	 else
	      return AfxGetMainWnd()->PreTranslateMessage(pMsg);
}
