I checked again (Win 11, 144 ppi or 168 ppi, ease of access font size 100% or 150%), it should work.
Probably you did not assign the new OnActivate handler. Because I did not tell you... In my first version of my post, I listed all the individual steps to patch the file, but this became very complicated, and I decided to send the completely modified unit instead. But I forgot about the lfm file which was modified by my steps as well.
So, please try again with the new attachment which now contains also the lfm file (unzip into components/ideintf of your Laz3.6 installation).
