I FIND A WAY GUYS.
Change those like that in the "Windows" Profil :
CMD A to CTRL + A
CMD Z to CTRL + Z
CMD Q to CTRL + Q
CMD W to CTRL + W
Everything working well now, i am happy, i tried hard for several minutes
You'v just saved my day (week, month...) Jojo !!!
The CMD+Q is mapped to ALT+F4 by default, changing to CTRL+Q is the solution !
For anyone looking for a solution after getting frustrated every time their work is lost because the application quits instead of selecting everything, Jojo's solution is the one! Go to Parallels Preferences, Shortcuts, select Windows, and in the list, find ⌘+Q, edit it, and replace ALT+F4 with CTRL+Q.
Thank you so much Jojo3 !
