Hi Bill - As you know, this one is likely going to be difficult to track down without adding some diagnostic code and/or logging network activity of the user. A few things: 1) Have you actually seen the problem occur? Is it possible that it’s just user error and they are clicking somewhere or possibly the back button? If would be very odd for a random direct to occur. 2) Do you have page caching enabled? Possibly something somewhere is cached? 3) Are all the pages Skuid pages? When a user “saves” is the user experience to stay on the same page or navigate away? If navigate, to where and using what technique? 4) have you checked your VF pages for anything that might be causing this? 5) Do you have any third-party JS modules loading on your pages that might be triggering the behavior? You’ve likely already thought of all the below but without a repro, I think your best bet would be to: 1) Sit with a user for a while and see if the problem occurs 2) Have the user capture video of themselves working and see if you can catch the problem and at least see it occur 3) Add some diagnostic logging to your pages 4) Enable logging of network activity for the user or have them capture browser network logs 5) Get a few gallons of coffee and spend countless hours trying to reproduce Not sure how much any of the above helps, but it’s where my head would be given your situation.

Ooh yes.  Gallons of coffee. 

Actually having users record a video of their work has been very helpful in these situations.
