I try update and have only this problem:
when I create a new mysqli connection with dynamic mysqli connection the connection file is created but isn't visible in database window.
Then all other windows (behavior and association) work well also with mysqli behavior but sometimes I need to close and reopen the file or click two o three times on the behavior and association windows for changing view and after all work.
My version is 2017.1 9583 italian on windows 10 64
