Hello to all,

I'm having the exact same problem.
Today, while working in version 2022.114, I printed several sheets of A3.
Then, in Qimage, I switched to another type of paper, and then opened the Full Page Editor window - and an error window immediately appeared:
       List index out of bounds (1)

At this moment, the programs were launched: Adobe Lightroom, Explorer, Notepad.
It was not possible to close Qimage by right-clicking on the panel icon - "Close Window"
I had to "kill" the Qimage process through the Task Manager.

When restarting Qimage, an error window appeared:
******************************
Qimage did not shut down properly last session.

Prior shutdown exit code: 15-run

Since you are running Windows 10, please be sure your Windows default printer
 has been updated to the latest compatible driver.
 Incompatible printer drivers can cause the driver to crash on startup.
If you have trouble using "Normal" startup, try "Safe" mode to start with defaults (ignore prior user settings).

How would you like to start this session?
Normal Safe
******************************
.. of course chose - Normal. Startup was normal.

I printed 1 sheet A3, and then when I tried to open the Full Page Editor, an error window appeared again:
 List index out of bounds (1)

.. again I had to "kill" through the Task Manager.


I don’t know if this is related or not - but FOR THE FIRST TIME Qimage began to hang here with me from version 2022.111.
  And I've been using the program since 2010 ...

In version 2021.111, the program began to freeze after trying to click on the button - disable the "Print by size (Auto)" option.
Then there was no error that occurred when trying to open the Full Page Editor window, but the program simply hung in a similar way.

Now I don’t see this button in the program interface, but the program still freezes sometimes, although in a different situation.


I hope my comment helps find and fix the problem...
