I have read many posts on bugs, I read that many problems have been solved. it does not work for me at all.

please find real solution

these the problems with illustrator
- the program is very very slow, almost still
- the pointer selects paths of objects without a voluntary action
- the pointer makes endless selections on the sheet
- the top menu does not respond or does so after many attempts
- almost impossible to open color setting panels
- very slow response keyboard functions (eg show as a path)
- unusable
- function block even if the program block is not signaled in the Force Quit panel
- Deactivation of all fonts

I have tried to:
set up documents in both RGB and CMYK
set the screen size to
cancel preferences
activate GPU acceleration
disable GPU acceleration
cancel and re install CC18
Screen resolution 1024x768
Screen resolution 1280x800
