Just to let you know, currently in the latest beta the following (I think) necessary changes are not yet included:
// DELETE and CTRL
if AllowDelete and
((sc = IEGlobalSettings().KeyboardShortcuts[iesDelete]) or
(sc = IEGlobalSettings().KeyboardShortcuts[iesCut])) and
not (loPreventLayerDelete in fLayerOptions) then
These changes are necessary for the event to be fired with "ielRemoved", aren't they?
