c++ - Modless CMFCPropertySheet with PropSheetLook_OutlookBar parented to a CFrameWnd -

when create modless cmfcpropertysheet set propsheetlook_outlookbar , parent cframewnd window created correctly mfc asserts when close window.

here assert

from gathered, crash happens in docking manager (the outlook bar "docked" rest of propertysheet) , it’s because parent window of cmfcpropertysheet derived cframewnd instead of cframewndex cannot change parent window cframewndex because breaks rest of application.

also bug happens when propsheetlook_outlookbar used.

my question is: there way use propsheetlook_outlookbar when parent window derived cframewnd? or doing wrong somewhere?

thanks you
