/***************************************************************************\
 *
 * METHOD:  FArePropertySheetsOpen
 *
 * PURPOSE: Checks if there are propperty sheets open and asks to close them
 *          It is implemented as the following steps:
 *          1. Collect all property pages (and their children) to the stack
 *          2. Bring all the pages to the front, maintainig their z-order
 *          3. Disable all those windows, plus MMC main window to disallow switching to them
 *             untill message box is dissmissed
 *          4. Put all disabled windows to the stack, to be able to re-enable them
 *          5. (if there are any sheets) display message box asking to close the sheets
 *          6. Re-enable disabled windows
 *
 * PARAMETERS:
 *    CString* pstrUserMsg - [in] message to display
 *    bool bBringToFrontAndAskToClose [in] if need to proceed whole way. false -> just inspect and do nothing
 *
 * RETURNS:
 *    bool - [true == there are windows to close]
