I don't know where I went wrong so I haven't a clue where to start in resolving this.
On my desktop, in Xfce, my Shortcuts are now using the plain text icons rather then the icon that is in the .desktop file. When clicking on them, instead of launching the expected application, it just opens in Mousepad.
I tried searching the forums and Google. But I can't seem to find the right keywords to get anything helpful.
