[Evergreen-general] Issues with Hatch and Chrome

Wed Dec 8 16:17:34 EST 2021

We are seeing this at CW MARS, too. (Evergreen 3.5.?, Hatch 0.3.2).

So far it has been random workstations at our libraries. The workstation
always uses Hatch, and disabling the Hatch extension makes Evergreen work
again.

We have suggested many things, (such as updating Windows, Chrome, etc -
reinstalling Hatch...), and nothing usually sticks.

We will have to try this:

I hope someone stumbles on a more permanent solution.
