Tide time displays on graph.

Since I upgraded to the latest version of WD in addition the sunset/sunrise markers I have a couple marking the tides positions as I have other arrangements for the tidal information I would like to turn these off, but in spite of going through the various menu items and the Q&A files I have not found this facility, can someone please enlighten me?

delete the tide times data from the wdisplay.ini file
[High tide]
[Low tide]
sections
when WD is not running
then make sure WD is not updating the tide info under view, tides (ie the switch is off there0

also
delete the tidein.txt file from where WD is installed
