I have made my own Normal.mxt template in order to set my toolbar defaults the way I like.
Since upgrading to 10.3.1, no amount of adjustment to the Normal.mxt template will 'stay put' as my default toolbar settings. It's like the normal.mxt no longer controls the toolbar in default mode or it ignores it completely.
I also recently installed the Geofacets add-in, and annoyingly, no matter how often I try to override the Normal.mxt template, Geofacets Add-in starts in every single map (even one's where toolbar settings are saved to map and Geofacets was specifically NOT saved in the toolbar). It's so annoying to have no tools every time I start Arc. Why won't my MXT's take in 10.3.1? Anyone having this same issue?
