I lose my page configuration to a especific size so i can save it as pdf without croping, everytime i close the aplication.

Can i set something as a default so that stop happening?

Are you running a script? Are you using Print Setup script step? What's the default Print Setup (File>Print Setup)?

Its not to print, its to save as pdf.

What my script does is:

1. go to a specific layout,depending on previous setting.

2. write something on a field depending on the account.

3.save as pdf to a specific location.

4.send a email with this pdf attached.

Im running that on a server.

Then for some reason even after fixing the page size, it simply dont stick as i left it.

It work, but after a while it begin croping again.

When do you specify the Print Setup (which is used by the Save as PDF)?

btw, saving Print Setups are known issues with FM9, see FMI's Knowledge Base, search "Print Setup."
