Hi pluiepoco !
To know your I.E. version, you have to click "?" and a thing like "about internet Explorer"
i don't know chinese term of your browser
To make a screenshot, press the key "Print Screen" at the right side of F12 touch... (i don't know chinese keyboard

) but i think the key could be here.
Then you open a program like Paint (or another to edit photos) and select Edit - Paste.
It will paste your "print screen" / you save it in the .jpg format and send it to the engeneer Bernhard
i hope it can help you
Thanks for your new design

but i can't read last name of the last post, is it normal ? or my browser ?
and all links are underlined :-/
