Edit Predecessor Form will not appear in the Predecessor column
I am trying to add lag time to a project but when I hover the mouse in any cell in the Predecessors column nothing happens. The Edit Predecessors form does not appear. Please help, I've tried everything.
"To make changes to the relationships between dependents and their predecessors, click Edit Predecessors (hover the mouse in any cell in the Predecessors column). From the Edit Predecessors form, you can change the relationship type or add lag time."
