Re: pgAdmin 4 v1.3 fails to load

I just upgraded to 4.1.3 and am having the same issues. Windows 7 pro,
x64, Postgres 9.6.2. Prior version of pgadmin 4 worked OK. (I skipped
the 4.1.2 upgrade, using pgadmin 3 instead to do what I needed.)

Same error; various scripts fail to load. It seems to fail more often if
the system is busy with cpu or disk activity already going on.
