Can't get measure tool units back to decimal degrees

[MichL]

I am at my wits end with this and am looking for some assistance.  I was using the measure tool and it was displaying in decimal degrees as I wanted.  Then I changed it to meters temporarily and then wanted to go back to decimal degrees, but no matter what I do I can't get it back.  I followed these instructions from Arc desktop help online Specifying a coordinate system—Help | ArcGIS Desktop:

 

and my data frame is set to display in decimal degrees, but the measure tool is still displaying meters.  What am I missing???

Is "New Data Frame 2", the active data frame? You need to activate the data frame, if already not active.

yes...it was the active data frame

Maybe one workaround is creating a new data-frame with a Geographic Coordinate System (same as the older one). Use the measure tool once again to get the values in Decimal Degrees. Even if you activate the older data-frame now, the units should be back to Decimal Degrees. Just needed to deactivate the Distance Units. I did not find an easier method to do this.

That seemed to work.  Thank you!!  Frustrating that decimal degrees isn't an option in the units drop down
