I have a couple places with a pencil/edit button that will take a user to a detail layout for a related/child record. I'm doing this with a button that just does a GTRR (not calling a script). Depending on the circumstance, sometimes it does it in the same window, sometimes it does it in a new modal window. I always have "Show only related records" and "Match current record only" for these. Works great on the Macs all the time. Works great on Windows… most of the time.
For one of my Windows users, occasionally (like once every day or two) it doesn't work. It appears that instead of performing the GTRR, it instead does a "Go to [First]" record in the same layout. So they expect to go to a detail or purchase order for job X, but instead they are suddenly looking at job A.
Here is a screen shot of my button setup:
