Hello, EmmanuelG. All is ok now.
After my old post
1) I reverted to 1.9.4.5
2) BUT after your answer, I reinstalled 2.0
What have i seen
1) I had to renew all my options, and finally I had what i wanted: small. Then I decided to test again 2.0, after your answer.
Before updating I marked Deleting data during uninstallation to clear everything.
After update
2) Eg-attachments menu on top of admin page hadn’t Eg-attachments templates voice in it
After some time (caching problem(?)), it appeared, but the css list was empty.
I tried a new option: i created a My css and saved.
Finally I saw all your css, and mine.
And now all is ok, TinyMCE css menu is populated, changing option is ok.
You’ve done a big and powerful work. Many thanks.
Example in my site
