Thanks. I've downloaded this software this morning with some others, and I try to understand how to use them.
OBS seems to be the most user friendly, so I'll try with this one ^^
EDIT : I tried, but this sofware doesn't record the different menus and contect ones. So it's impossible to see on what I've clicked and what I've chosen/done when I have another window or menu. I don't know if it's possible to fix that. I've tried to configure everything in vain ^^"
Edit Edit : Oh ! I think I've found : clicking on the Fade to Dark stuff have moved the screen display to the right. And now, the context menus are recorded ^^"
