I remember this kind of occurrences and some of theme are caused by some elderly PlugIns.
Are you using any PlugIns? If though, would deactivate all plugins for testings change anything on this behaviour? Do you use most actual updates for all Plugs?
Thx for your prompt help.
This is a new clean install. FM Pro Advance 13.0v1. Layout is River.
Thank you for your posts.
Starting with FileMaker Pro 12, the arrows no longer appear to the left of the script steps. You simply drag/drop the script step to the desired location. For example, in your linked screen shot, if you highlight the New Record script step, you can then drag it upwards to a different location, let go, and the script step will be moved to that new location.
Let me know if you need additional clarification.
Thank you for your help.
Your answer explained my doubts. I was watching a tutorial and there was this example with arrows.
Once again thank you.
