Just when I thought everything was the way I want it and working nicely in my Wary Puppy 5.5 Frugal installation the Shutdown Menu items stopped working. I checked all the files: wmreboot, wmexit, wmpoweroff, and restartwm. They are all in usr/bin/ as they should be and their permissions are all correct. The file wm-xdgmenu is also there.
I can only shut down now using Ctrl + Alt + Backspace.
Prior to this happening I was using Puppy Package Manager to download a number of different things that I thought might be useful or appeared to be later versions of things I already had installed. I forget what all of them were. After one of these installed (I forget which) all my icons changed. I don't know if that is related.
