Organiser

I have just bought Elements 2021 mainly to use Organiser but I find it buggy and clumsy. When I move from one directory to another on the directory tree the screen flickers and after a few seconds the screen returns to the previous directory for a split second before settling into the directory I am trying to view. All that accompanied by more flickering of the screen. Is there a cure for this?

I bracket my exposures so usually two thirds of my shots are deleted. To delete an image in Organiser however I need to select the image, press delete, then check the box to also delete from the hard disk and then hit OK. That makes the process take three or four times as long. I want to select, press delete and gone from the catalogue and from the hard drive. I could do that in Bridge, why can't I do it here?
