IrfanView does not ask before deleting

I want to set IrfanView at my Windows 10 to ask me always before deleting a file (moving it to the trash).

There is an option in Settings -> File Handling -> Delete: Ask me before deleting files (if activated in Recycle bin settings) - I have marked this option and also Delete to Recycle Bin. See image below.

But any confirmation message does not show if I press the Delete button and the image is instantly moved to the trash.

I tried IrfanView version 4.52 x86, 4.52 x64 and 4.51 x86 and it is always the same.

How can I fix it?

Any confirmation message does not show if I press Delete

Have you checked your Recycle Bin settings? "Display delete confirmation dialog" must be checked there for this to work:

1. Use Windows+D shortcut to view the desktop.

2. Right-click the Recycle Bin icon, and select the Properties option.

3. Check the Display delete confirmation dialog option.
