Now using 12.3 but cannot find the option that used to be shown by right clicking the chart window that showed "properties" of the chart nicely listed in order. Has it been discarded or is it hiding somewhere?

I still have a "Chart Properties" option available when right-clicking on the chart. It gives options for Price Plot Style, Drawing on Chart, Colors & Grid and Edit Toolbar. I suspect you want the Colors and Grid option.

I get those four options as well.  But in prev. vs. I could get a display of all the indicators in each of the panels that then could be edited by right clicking and  hitting "properties"

I use TC2000 version 12.3 a lot and do not recall ever having such an option available.

In TC2000 Vs 7 when I click "Edit" at the top of the chart (jjust to the left of the time frame link) a window would appear showing all the indicators in the three window panes and the abiliity to alter them. I found this very convenient and miss it in Vs 12.3

Thank you for your suggestion. It has been assigned case number 10489.
