That's a frustrating one. How are you using the formatting tool bar in the original window? Perhaps you can do without it by adding buttons to your layout that perform the same function as what you are doing with the formatting tool bar on the original layout.
I just turned it on, so I'd have it as a developer, but I had no idea that New Window would mimic that behavior, until now. I suppose I'll just show it when I need it, and hide it when I'm done.
That is a confusing aspect of FileMaker...I would think the default behavior is to have those sorts of things off, and if you want to show them to the user, it should have to be specified. When I showed this layout to another user, using the hosted file from the server, his layout opened with the status bar on as well. It seems to just remember the last setting that was used the last time it was open.
I reported it as an "Issue" here on this site. I got the answer:
"Allow Formatting Bar" script step.
Why didn't they call it as "Show/Hide Formatting Bar", so that it would appear in the same place when sorted by name? It is functionally the same type of step as the other two Show/Hide steps. This just makes it harder to find.
BTW, I tried using it, and it works.
I had a nagging echo in the back of my mind that there was such a step, but I didn't see it when I went looking for it. I haven't had to make regular use of it as I prefer to keep the entire task and formatting bar hidden away from the general user.
