This is a bug report, I think.

After applying security to a form, I can still edit the tab order. I added a permissions password and allowed filling in form fields. After saving to apply the security, I opened the Prepare a form tools. From there, it allowed me to drag and drop to reorder fields in the fields pane, let me save my changes, and those changes were there after closing and reopening the file.

Since I applied security this should not have been possible. But I tried it multiple times and in different files, and each time it let me change the tab order even with security applied.

I'm using Windows and this happened in both 2024.005.20320 and 2025.001.20474 .
