Hi guys I'm having this weird problem with the linuxmint-14-xfce 32bit distro that started after my sister used the pc. For some reason the close program and minimize window controls are missing from the top of all the program windows. My sis says she didn't do anything so I'm not sure how it could have happened. I've used a lot of different linux distro's and this is the first time i've seen something like this. Pics are below.
