Intercepting Save and Save as

A long long time later, and I too have found this issue.
FWIW, I've settled on using the toolbar OnIconSelection event and this filter:

if (group = 1024) and (num = 4) and (index = 0) then
begin
// save
Typ := wptNone;
Save1.Click;
WPToolBar1.DeselectIcon(index, group, num);
end;
