Has anyone had an issue getting grid prefs to “stick”? My grid keeps resetting itself to 0.1, no rulers. I change it, hit Save Defaults, then goes right back to 0.1.

It seems to happen when I switch from an ortho view to persp, turn off grid, then switch back to ortho (with grid off). Pulling up the grid settings dialog at this point shows (greyed out) 0.1, no rulers. And sure enough, if I turn grid back on, it's reset itself.

I can confirm that the prefs file gets written with Save Defaults, and that the grid setting is in there & correct.

This is H15 15.0.326 on Windows 7. And it's irritating as all heck.
