When using Adobe Acrobat Reader DC as the editor, the document will not automatically save before being returned to FormPro. This issue is caused by Adobe's "protected document mode" security feature which is enabled by default.
### Symptoms:
- Save as dialog is displayed when you click the blue "Send to FormPro" button.
- Data changed on the form is not saved to FormPro, missing in subsequent merges of data.
### Observed:
- FileMaker Pro 19.0.1.x on Windows 10, Acrobat Reader DC.
- This does not affect MacOS computers using Acrobat Reader DC.
### RESOLUTION
Under **_Edit > Preferences > Security (enhanced)_** Change the following setting:
- Make sure the "Enable Protected Mode at Startup" checkbox is NOT checked.
- Click "OK" to save settings.
### Temporary workarounds:
- You can save the data to FormPro by manually using the File > Save As dialog and overwriting the existing PDF in the **__/documents/FormPro/** folder.
- After saving the document manually, the blue "Send to FormPro" button will function as intended.
- Also advised is to go to acrobat preferences, general tab, and uncheck the "show online storage when saving files" checkbox.
- You can also try using an alternative PDF editor, like FoxIt or NitroPDF.
