I am using linux mint 15 with MATE 1.6.0. The problem i am experiencing is that when i am opening a folder ( ex: home, my computer, etc ) for the first time, the minimize, maximize and close buttons won't work. In order for them to work i have to minimize the window from the taskbar and maximize it again. After this action the buttons work just fine. Sometimes after the minimize and maximize action, when i try for example to minimize that window it minimizez the inactive windows in the background if i have more windows opened simultaneous. I would really areciate the help.
