I am not sure exactly what kind of a desktop I am using (under f11 - I have software from the five continents) and I noticed when working on the computer two inconveniences.
1. When copying some files. on the USB drive I cannot take away the USB card (for the copied files are usually damaged without issuing a bug report). I had to shut down the computer for everything to be O.K.
2. When copying a disk by the DVD Gnome Backer (it is much faster than the one going with F11, burning directly on the DVD/CD) and after closing the program by the GUI, the program is not closed (issuing a bug report) but everything with the disk processing is usually O.K. (I apologise if this issue has to be addressed to somebody else).
