I am using FC 880 Public on Windows 11 Home.

I always use the folder panels in Details view mode (CTRL+F2).

I am also using three plugins to view the items in QuickViewer:

1. sLister+SumatraPDF
2. uLister+Oracle Outside In Technology
3. multimedia

All the plugins worked just fine.
But I have started facing a new problem in sumatraPDF, starting from version 3.5.

The details are as follows:

When I was using older versions of Sumatrapdf (till 3.4.6), even after I activate the QuickViewer, the focus remains in the folder panel.
As a result, I am able to use UpArrow and DownArrow to rapidly move up-down and check the preview of those items in the QV panel.

But starting with 3.5.x versions, SumatraPDF behaves differently: It immediately steals the focus to QV.
As a result, if I press UpArrow and DownArrow, the display in the QV moves up-down, rather than moving the focus to the next/previous item in the Folders panel.
I am not able to rapidly move through the items in the folder panel and check out their previews in QV.

I have used all versions of SumatraPDF one by one, and positively confirmed that all versions till 3.4.6 work fine, and all 3.5.x versions have the problem.
In other words, the behavior has changed in the 3.5.x versions.
Therefore, this seems to be a conscious design change in SumatraPDF.

So the question is, how can I restore the previous behavior?

Is there any setting hidden in the sLister subfolder that I can change?
(e.g. in the sLister.ini file, or SumatraPDF-settings.txt file?)

Thanks in advance!

I assume you have also asked about this on the forum of SumatraPDF?

This is a known problem with the new 3.5 SumatraPDF versions.
Currently no solution,
so you have to stay with the latest 3.4.6 version.
