How to Resize the Custom Scan Window in Adobe Acrobat XI
Question details
The user is unable to access the bottom controls in the Custom Scan window of Acrobat XI Pro because the dialog box is too large for their small display.

- Product
- Adobe Acrobat XI Pro
- Device & OS
- Windows
- Scenario
- Attempting to configure scan settings and execute a document scan on a small 10-inch display.
- Observed behavior
- The Custom Scan dialog window extends beyond the screen boundaries, making the action buttons and controls at the bottom completely hidden and inaccessible.
Ensure your scanner is properly connected to your device and save any open work before making changes to your system's display scaling settings.
Use Keyboard Shortcuts to Move or Resize the Window
Use Windows built-in keyboard commands to force the oversized dialog window to move upward or shrink, revealing the hidden buttons.
Older applications often use fixed-size dialog boxes that do not adapt well to small screens. Using keyboard shortcuts allows you to manipulate the window without needing to click its borders.
While the Custom Scan window is active and selected, press Alt + Space on your keyboard to open the hidden window management menu.
Press the M key (for Move), then use the Up Arrow key on your keyboard to drag the window higher up on your screen until the bottom controls are visible.
If moving it is not enough, press Alt + Space, then press the S key (for Size). Use the arrow keys to shrink the window's bottom or side borders.
Once you have revealed the hidden scan controls, press the Enter key to lock the window in its new position or size.

Adjust Windows Display Scaling
Lower the system display scaling percentage to fit larger dialog boxes onto small screens.
Update Scanner Drivers and Software
Ensure your software and scanner drivers are up to date to resolve compatibility and display scaling bugs.

Frequently Asked Questions
Why are the buttons hidden in my Acrobat XI scan window?
This typically occurs on smaller screens (like 10-inch displays) or when Windows display scaling is set above 100%. Acrobat XI is older software with fixed-size dialog boxes that cannot resize dynamically, causing the bottom controls to be pushed off the screen.
Can I force a window to resize if I can't see the edges?
Yes. You can press Alt + Space to open the window's context menu, press S (for Size), and then use your keyboard's arrow keys to shrink the window borders, even if you cannot see or click them with your mouse.
Is Adobe Acrobat XI still supported for bug fixes?
No. Adobe Acrobat XI reached its end of support in October 2017. It no longer receives official bug fixes, which is why display scaling issues on modern operating systems remain unpatched.
How do I access hidden window controls without changing system settings?
You can use keyboard navigation by pressing the Tab key repeatedly to cycle through the available inputs in the dialog box. Once you believe the hidden 'Scan' or 'OK' button is highlighted, press the Enter key to execute the action.
