Mounting usb sticks the manual way (as root) makes them read-only. I put this
line in /etc/fstab so they mount without restrictions.
/dev/sdb1 /mnt/usb auto users,noatime,umask=0 0 0

Also, I had issues with Spacefm and Caja dealing with removable media. Caja
would complain 'could not display computer ///' and 'cannot handle computer
locations'. I found that the best so far screen capture app is the Xfce
'xfce4-screenshooter'. I had issues with the Gnome screenshot program (it
started misbehaving, 'segment fault').
apt-get install xfce4-screenshooter
