I don't believe there is a way to prevent users re-sizing, re-positioning or changing the zoom for a form.
These are features that enable users to have forms open in a consistent manner.
There is a process that will enable users to reset the form position and size to the default.
There are 3 options to do this:
- You are then prompted for parameters - Press F3 for a list of options
- Select F - Saved form position cache
2. /CLEAN.SBHSTATE F
- You will not be prompted as you have already provided the option to clear Saved form position cache
3. You could also create your own process to do this:
Paragraph - CLEAR.FORM.POS
Let me know if you have any questions
