Hello,
I haven't used the dialog_ng module, but (as expected based on the
dialog module) if you only set the FLT_DIALOG flag, then the dialog is
created when calling t_relay(). The dialog module has dlg_manage()
function which creates the dialog immediately, maybe that's in dialog_ng
as well.
Cheers,
Daniel
