How to save HyperView visualization preferences?

I'd like to change the default display options in HyperView. I loaded the .mvw file that was attached to the following article about HyperView model information options (Tutorials, How To, Troubleshooting - How to customize Model Info note in HyperView? (altair.com)).

Next, I made three changes in the HyperView session:

• graphics window background color (with a tcl command)
• changed the display settings of the model measures (had to load in results to do this)
• configured the model notes field

I then saved a new .mvw file in order to make the updated preferences default using File > Load > Preferences, but I can't find the option to assign the new file as default. Furthermore, when I try to load in the new preferences file in another session of HyperView, none of the settings are changed. I'm sure that there are multiple layers of things I'm doing wrong here, but provided a description of my attempt for a little more context.

My question is: how can I save the three listed display settings such that they are loaded by default when a new HyperView session is launched?

Thanks,

Mandy
