Some dialogs have checkboxes for actions like "don't show me this ever again". Is there some setting somewhere that undo checking those boxes? So that the dialogs will appear again? I'm specifically focused on an editor wanring,"Spatial reference does not match data frame" which has the checkbox "Do not show this dialog unless there are errors that prevent start editing". Someone is advising me to check that box, and I don't want to do that until I know I can get this time of warning to show up.
