Scenario
Interacting with a fillable PDF form and attempting to submit the entered data using a custom submit button.
Observed behavior
The computer freezes and spins in an endless loop upon hovering over or interacting with the submit button, requiring a forced quit of the application.

Solution 1Recommended

Change the Button Event Trigger to Mouse Up

Replacing the continuous 'Mouse Enter' trigger with a discrete 'Mouse Up' action prevents the system from getting stuck in an infinite submission loop.

A common cause of freezing is configuring the submit action to trigger on 'Mouse Enter'. Because the mouse stays over the button, the event fires continuously, overloading the application. Changing this to 'Mouse Up' ensures the action only fires once after a complete click.

1
Enter form editing mode

Open your PDF form in Adobe Acrobat and navigate to the 'Prepare Form' tool to enter editing mode.

2
Access button properties

Right-click the problematic Submit button and select 'Properties' from the context menu.

3
Modify the trigger action

Navigate to the 'Actions' tab. In the 'Select Trigger' dropdown menu, change the setting from 'Mouse Enter' to 'Mouse Up'.

4
Save and test

Click 'Close' on the Properties dialog, exit the Prepare Form tool, save the document, and test the submit button.

Change the Button Event Trigger to Mouse Up
Best Practice: Always use 'Mouse Up' as the standard trigger for interactive buttons in PDFs to guarantee reliable execution across different PDF viewers.

Frequently Asked Questions

Why does the 'Mouse Enter' trigger cause my PDF form to freeze?

The 'Mouse Enter' trigger fires continuously as long as your cursor hovers over the button area. For a complex action like form submission, this rapid, repeated triggering overloads the application and causes an infinite loop, freezing the computer.

How can I view JavaScript errors in Adobe Acrobat?

You can open the JavaScript Debugger console in Acrobat by pressing Ctrl+J on Windows or Cmd+J on Mac. This window displays syntax errors or runtime warnings that may be causing your interactive buttons to fail.

Can I fill out interactive PDF forms without using Adobe Acrobat?

Yes, many modern PDF readers and comprehensive suites like WPS Office fully support viewing, filling, and submitting interactive PDF forms flawlessly and often use fewer system resources.
