You should read the thread more closely. You can't use the old
"screenbuffer" method, because unlike TOS, N.AES, Geneva and (maybe)
MagiC, XaAES menus are *not* blocking other applications. So the
contents of the window behind an open menu might have been changed since
the menu was opened. That's why it's necessary to use ordinary redraws.
