I’m not sure what it is about Mint 17, but I’ve been having a strange problem with programs just refusing to launch. If I watch the system monitor, I can see the file get loaded into memory, but then it goes zombie on me and then quits. This has happened to a good dozen programs over the past month.
If this happens to you, it’s pretty easy to fix though. Just open your Package Manager, find the program that is misbehaving, right click on the program name and mark it for reinstallation.
This problem has cropped up with the System Monitor, Caja, and a couple of other important programs. Tests on my hard drive and memory all report everything as fine. Guess I’ll just wait it out and see what happens.
