[Evergreen-general] Inconsistent White Screens with Hatch

Tue Nov 7 16:58:16 EST 2023

Diane,

Did they still disable the Preload Pages setting? While only Hatch
libraries have reported the issue in my network so far, I wouldn't be
surprised if it could affect non-Hatch workstations, too. I'd still disable
the setting to see if it helps.
