how to keep frame counter from clobbering toolbar hints

in CMainFrame::OnNotify:

case AFX_IDW_TOOLBAR:
    if (nmh->code == TBN_HOTITEMCHANGE) {
        LPNMTBHOTITEM   lpnmhi = (LPNMTBHOTITEM)nmh;
        if (lpnmhi->dwFlags & HICF_ENTERING)    // if entering toolbar
            m_HideFrameCounter = TRUE;  // hide frame counter
        else if (lpnmhi->dwFlags & HICF_LEAVING)    // if leaving toolbar
            m_HideFrameCounter = FALSE; // show frame counter
    }
    break;
