Well, after thinking again I wasn't sure anymore that the problem was (only) the screen, as also the keyboard and mouse were missing... So I didn't know (and actually don't know now too) if it's the screen, the keyboard, the mouse or all of them...
I used the screen, mouse and keyboard to select several files and create a .zip file (by drag & drop.)
I've changed it by performing command line actions, namely launching winrar and using "program parameters" to tell winrar exactly what to do.
Works flawlessly
Best regards,
