Subject: Resolves: tdf#122219 base form writer-window doesn't honour CloseVeto
 properly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

just hit this with the same all-modal hammer we now use in the extension manager,
a modeless dialog, with modal subdialogs run by a normal non-async subloop, turns
into a modal dialog for all other toplevels
