Trying to get find image and mouse click to work

I have several possible ideas:

  • If it works in Brave but not in Chrome, I suspect that this is because you snapped the image while in Brave, but the image in Chrome is slightly different (more likely a different size.) Each browser has its own zoom level, and perhaps Brave and Chrome have set their zoom levels to different values.
  • Have you tried rebooting the KM Engine lately? Depending on your amount of RAM, Find Image can fail to work after a long uptime. I usually reboot weekly on my 24 GB Mac in order to prevent problems with Find Image. On my old 8 GB Mac, I had to reboot daily, sometimes hourly.
  • Is Chrome the active front window when you are doing your image search? According to some posts, Chrome has a bug that prevents that from working correctly:

Yes...

As for "main window" I don't understand what that term means. In any case, your questions about windows are probably pertaining to your Find Image issue, right? Are you asking about one of the pull-down menu items in the Find Image action? There is no "main window" option but there is a "main screen" option.
