Question details

The user needs to restore the Acrobat debugger window to a usable size after a long line of text caused it to expand beyond the display boundaries.

How to Reset an Oversized Adobe Acrobat Debugger Window
Product
Adobe Acrobat
Device & OS
not provided
Scenario
Using the Acrobat debugger console when an extremely long line of text stretches the window out of bounds.
Observed behavior
The debugger window expands so much that it goes off-screen, hiding the console and the top toolbar. Restarting the computer or attempting standard resizing methods fails to resolve the issue.
Before you start

Before attempting manual window adjustments, try disconnecting any external monitors connected to your computer to see if the operating system automatically forces the Acrobat window back onto your primary display.

Solution 1Recommended

Manually Reposition and Resize the Window

Use a repetitive drag-and-resize technique to manually bring the oversized window boundaries back into your screen's viewable area.

Because Adobe Acrobat often remembers the last window size—even if it is excessively large—restarting the application usually does not fix the issue. You will need to manually alternate between moving the window and shrinking its edges until it fits your monitor again.

1
Move the window downward

Click and hold any visible portion of the debugger window's title bar, then drag the window downward until the top edge is well below the top boundary of your screen.

2
Resize the top edge

Hover your mouse cursor over the top edge of the window until it turns into a double-sided resize arrow. Click and drag the edge downward to shrink the overall height of the window.

3
Drag the window upward

Click the title bar again and drag the entire window back up toward the top of your screen.

4
Repeat until resolved

Repeat this process of pulling the window down, shrinking the top edge, and moving it back up until the debugger window is small enough to see the console and toolbars clearly.

Manually Reposition and Resize the Window
Use Keyboard Shortcuts on Windows: If you cannot reach the title bar with your mouse, select the Acrobat Debugger icon on your taskbar, press Alt + Space, type 'M' for Move, and use your keyboard's arrow keys to bring the top of the window into view.

Frequently Asked Questions

Why does the Acrobat debugger window become oversized?

The debugger window can expand out of control when it logs an unbroken, extremely long string of text or code. Because the application attempts to display the line without word-wrapping, the window stretches beyond the physical limits of your monitor.

Why doesn't restarting the computer fix the window size?

Adobe Acrobat frequently saves the last known coordinates and dimensions of its windows to user preference files. When you restart, the application simply loads those oversized dimensions again rather than resetting to a default size.

How can I prevent the PDF debugger window from expanding off-screen?

To avoid this issue, prevent your PDF JavaScript from outputting massively long strings into the console. Additionally, regularly clear the console output while debugging before text lines get too long.

Is there a way to reset Acrobat preferences to fix the window size?

Yes, holding down the Shift + Ctrl + Alt (or Shift + Option + Command on Mac) keys immediately while starting Acrobat can reset its preferences, which may restore default window sizes, though it will also erase your personal settings.
