rehabilitate right-click menu in mechanical desktop

[Besadogo]

Hey, guys.
with a 2009 mechanical desktop, something strange ever happened to me: by clicking with the dx mouse button I carry out the last given command and I can no longer see the classic curtain showing the comendi move, copy, properties etc...
Can you help me?
greetings
