Write access to the File system

Unfortunately it's unusable.
When I uncheck the protection mode Acrobat takes about 10 to 30 seconds each time I click to select a field or change page. And the more scripts the document contains, the slower it is.

I lost about half a day's work trying to work out what the problem was.

Thank you

Try this:

In the preferences disable the protection mode.

Please, please!
