I do parcel edits daily and until today have never had the edit vertices toolbar popup when I start to edit a parcel or line. I have not updated anything on my computer nor on ArcMap today or yesterday. I have tried everything I know to try to turn it off so that I can continue to edit as I have previously done. I have unchecked it on the editor options and turned it off on the toolbar list on the customize tab. My ArcMap project is running extra slow also today and I assume that this toolbar has something to do with this also. Typically, when I click a parcel or line, the item will be selected almost immediately, but today when I select a parcel or line the project just sits and spins.
