If a given popup pops up another dialog, then this is treated as part of the "stand-alone" operation of the first dialog. Associated files: None. Invocation: OffsetPopups [runType] [offset] "runType" controls which dialog to surface in "standalone" mode as follows: "p" for parent, "c" for child, or "g" for grandchild, "gg" for greatgrandchild. Parent is the default (and of course "standalone mode" has no meaning for the parent dialog, as when run it's always the root dialog. "offset" is a number that governs the extent to which a descendant dialog is visually offset from the ancestor that surfaced it. The default is runtype = Parent and offset = 0.
