Here's a change request how ZTree could avoid this:

a) Outside of Viewer, #ZTLine is Zero anyway (no counting).

Inside of Viewer:
b) when Line mode is Off, Viewer does NOT YET need to know which line it stands on.
Only if you press e[X]ecute or [E]dit or Alt-[E]dit, Viewer has to count lines once,
in order to provide a value for the #ZTLine variable  which may be used there.

c) If Line mode is switched On, Viewer has to keep track of the Line number  (slows it down).

d) If Line mode is switched Off again, return to rule b).
