How to Fix an Acrobat JavaScript Window Too Large for the Screen
Question details
The user needs a way to resize or move an oversized Acrobat JavaScript window that spans multiple monitors and hides essential interface elements like the OK button.

- Product
- Adobe Acrobat
- Device & OS
- Windows
- Scenario
- Opening the JavaScript debugger or executing scripts in Adobe Acrobat, especially when using a multi-monitor setup.
- Observed behavior
- The JavaScript window stretches beyond the screen edges, introducing a horizontal scrollbar, hiding the OK button, and reverting to the oversized state when the title bar is clicked.
Save your current PDF documents and ensure you have access to your Windows display settings, as you may need to adjust screen scaling to reveal hidden interface buttons.
Use the Windows System Menu to Move or Resize
Utilize Windows keyboard shortcuts to access the hidden system menu, allowing you to manually move or shrink the oversized window without using the mouse.
When a window is too large and the standard resize handles are pushed off-screen, Windows provides a keyboard-driven method to manipulate the application window. This bypasses the UI bug inside Acrobat.
Click anywhere inside the Acrobat JavaScript window to ensure it is the active application.
Press 'Alt + Space' on your keyboard. This will open a small system menu, even if the title bar is off-screen.
Press 'M' to select Move, or 'S' to select Size. Use the arrow keys on your keyboard to drag the window into view or shrink its borders, then press 'Enter' when you are done.

Temporarily Adjust Windows Display Scaling
Change your monitor's display scaling to a lower percentage to zoom out the screen and reveal the hidden parts of the Acrobat window.
Reset Acrobat Preferences
Clear Acrobat's saved window layout configurations to prevent the JavaScript debugger from reopening in its corrupted, oversized state.

Frequently Asked Questions
Why does the Acrobat JavaScript window keep snapping back to an oversized state?
This is a known UI behavior or bug in certain versions of Adobe Acrobat, particularly when used across multiple monitors with different scaling resolutions. Clicking the title bar sometimes triggers the application to revert to its previously cached, oversized layout.
How do I click the 'OK' button in Acrobat if I can't reach it?
If the 'OK' button is hidden off-screen, you can often execute the command by pressing the 'Enter' key while the prompt window is active. You can also use the 'Tab' key to navigate through hidden buttons.
Will reinstalling Acrobat fix the JavaScript debugger window issue?
Reinstalling might help if the installation itself is corrupted, but resetting your user preferences folder or updating to the latest patch via 'Help' > 'Check for Updates' is usually more effective for resolving specific UI layout bugs.
Where can I report bugs like the oversized window issue in Adobe Acrobat?
You can report bugs and provide feedback directly to Adobe through their official Acrobat User Voice platform online, or by selecting 'Provide Feedback' under the 'Help' menu within the application.
