This is an odd one.
PCmanfm simply won't copy or move files. It is otherwise fully functional.
This is true regardless if I use keyboard shortcuts or try to drag files with the mouse. Simply nothing happens.
I tried to start the program with at the terminal so I could get a look at possibly what was happening, but this doesn't work! starting pcmanfm at the terminal works fine, but the command exits and doesn't display info while it's running. I've never seen that before, either.
In any case, I can't recall when this started happening, because the first time it occurred I just didn't think about it enough. Thinking maybe I was trying to do something without permissions, etc. But this is not the case.
I've been using Thunar instead, which works fine, but I'd like to figure this out if possible.
