Topic:
Unable to edit a posted horizon.

Description:
The horizon is posted on the seismic section and is the active horizon.
Re-picking the horizon does not alter the posted horizon.

Solution:
Check whether Interpretation Crossposting under Post > Interpretation is toggled
on.  A second seismic line, containing interpretation for the active horizon, on
top of or very close to the current line will result in interpretation
crossposting on all the traces, giving the appearance of actual interpretation
posting for the current line.
