Custom View Orientations in Creo Illustrate

[tmenadue]

We've noticed that our Custom View Orientations in Creo Illustrate have gone away. If we add new orientations, they do not reappear the next time we open something in CI. They were working prior to 4.0. Does anyone successfully use saved custom views in a version newer than 4.0?

I've attached the Custom Views Orientation window. We're having to update this with every new file. Not fun.

For a long time my custom orientations were saved by default.

But yesterday I had an issue while trying to save, so I deleted the %APPDATA%\ptc\Illustrate\user_prefs.xml file as suggested in this article:

And now they are gone. 
So I guess they will disappear if you have some sort of auto clean-up running over night.
