Unable to change LookupDropDownUseStandardControl property

Dec 29, 2016 at 5:50 PM
I need to change the "LookupDropDownUseStandardControl" property on the web application from TRUE to FALSE. This property was apparently changed by the SP1 install. I can change any other property value, but not this one. I click on the property, then pull down the dropdown list and choose FALSE, but it always stays TRUE.

Has anyone else run into this issue? I have full admin rights to the farm, but I've tried with both my own account and running as administrator. Same thing.
