My husband is still running Mojave 10.4.6 on his Macbook 13inn Early 2013
model.
A really weird problem has arisen. He can't open* any* file or folder in
any programme (Mac or otherwise) with his mouse or trackpad without going
to File>>Open or in Calendar>> Edit Event).
He's re-started his machine; installed a new mouse,  but he (and I ) are
out of ideas at this point because it's such a strange problem.
