Hi guys, I'm newbie on Linux, I installed Linux Mint XFCE, at the beginning everything was fine, after some updates I have the same problem, I can't see minimize, maximize and close buttons, and I can't change between windows, I mean, alt+tab doesn't work and when I open a new app this window comes in to the front and I can't change to the windows behind that, I click the other window and nothing happens.
Also the app that opened doesn't show in the panel bar. I try to change window behavior but window manager doesn't work, I can't do anything on window manager, shows only a blank window.
I read in other forum that right click to the panel, add panel, add window list, but still doesn't work.
I read that you say but I don't understand how to fix that, can you be more specific, the command to run.
Thanks in advance for your help.
