@sito1002 I have no issues. Did it work the other day? If so, maybe you just have corrupted preferences. Go to Preferences (Cmd K on Mac, Ctrl K on PC). Click the Reset Preferences button at the bottom. Click OK and restart Illustrator. Illustrator will cleanly wipe the settings file back to it's default settings.

Be advised, it will delete any custom workspaces and kyboard shortcuts, panel locations, tool settings, recent list
