A few facts: I use Wine. Wine ships its own version of Notepad. For some files, this copy of Notepad has somehow become associated. There is no possibility of me ever actually wanting to open anything in Notepad.
I figure I could try and find out what Notepad is associated with and re-associate that with my editor of choice but that seems deeply tedious. Is there any global way to stop Notepad existing as a method for opening files?
