Thanks again Barney. Turned off as much as I could find in both iPad and iPhone. When pitting January 3 in Notes on each did not automatically get the fraction but the hint to auto change which I could ignore (fine). Went back to the desktop and viola still the same problem. Still at a loss.
BTW - when I went to Stickies and tried to turn off substitutions there it refers back to the keyboard settings panel and it no longer substitutes. Tried same thing in Mac Mail. Looked the same as Stickies menu and changed so that they were the same but it still substitutes. Go figure! My main problem is having this occurring in Acrobat Pro bookmarks. Now that I am totally confused I checked a few other places. My next spot was Word which I knows does it owns thing. I checked there and added an Exception to AutoCorrect saying to omit converting January 3 (using / and numbers) to ⅓. That worked in Word but Acrobat still gave me fraction. I next looked at Excel and there was nothing there that I could see but the fraction problem occurs in Excel yet so it is picking it up from whomever else too. Checked One Note and same as Excel. On the off chance also checked to see if anything existed for this in Photoshop but no substitutions there.
Another interesting behavior using Stickies and Acrobat Pro. Remember Stickies no longer has any substitutions enabled. I am in Stickies and type the date it no longer inserts the fraction. I change to Acrobat Pro (click on open window), click back onto stickies and type the date it now substitutes again, however if I enter the date again it no longer substitutes . Go figure again!
I am officially out of ideas
VERY frustrating spending more time trying to get rid of "timesaver" than will ever save.
Thanks for listening - all ideas welcome.
