Thank you Jim!!!
I found your approach better than many others on the forum.
Building on your approach, I simplified it a bit for anyone else with the same problem – although I am pinning an object to the top of the page in my example.
In this example you can move the NavBar object wherever you want on the page. I also used a trick of making the main group a 1 pixel wide but full page long line so that it does not cover any other objects that may be underneath it.
Object fixed on scrolling page.zip (29.6 KB)
