Button dx mouse crazy

[mdbosca]

Bye to all,
from the latest update 2018.1.2 presents the following problem:
in the browser or in the selected part, right-click the drop-down menu appears/disappear immediately by operating the command near the pointer... Does it happen to you? Did you solve it somehow?
a despair, I'm tribulating. Thank you.

the problem happens only within inventor, other programs or cad, no problem
replaced mouse but.. the problem persists also with update to 2018.1.2
we don't know what to do
