Pivot shoe replacement

A quick learner from Vestal NY says:
Replaced using cut out method. Replaced window. Pushed window to top position to be open and it slides back down about 5 inches?? What did I do wrong?

Sounds like there isn't enough tension in the balance spring. Does this shoe work with a spiral balance? If so, it probably unwound a little when you swapped the shoe out. That's easy enough to fix, you just need to wind the spiral 1 or 2 times. See the video below for more information.
