Confirmed Thumbnails Folder Pane loses focus after thumbnail caching

[Emulgator]

Many thanks for developing IrfanView throughout the years !
My favourite viewer since 2004 and I became an early donor.

From Irfanview 4.54 on Thumbnails Folder Pane loses focus from folder pane after caching of thumbnails has finished,
instead moves focus to first picture.

This breaks my AutoHotkey script which allowed me to step through folders using up/down arrow.

SetKeyDelay, 0, 0
Down::
Send {Down}
Send {Alt}
Send o
Send u
return
Up::
Send {Up}
Send {Alt}
Send o
Send u
return

4.56 has the same behaviour, 4.52 kept focus on the selected folder.

Is there a way to have the 4.52 behaviour back ?

ALTGR+TAB cycles the focus through
1. thumbs panel
2. folder path at the top
3. folder tree

perhaps you can build on that with your script

I can confirm that the behavior changed. Previously, I was able to browse folders in the left panel using keys. Now, it jumps automatically to the right panel.

jazzman, good thought.
Will consider that if Irfanview stays unchanged.
