Unbeknownst to me, the version of the Lockdown Browser I have installed on the desktops, doesn’t play very well with Windows 7. I’m in the process of getting a new copy that is designed for lab use and that will correct the issue, but it will probably be a few days before everything is corrected. In the meantime, steer any students in need to either the thin clients or the laptops. Thanks!
As of Tuesday, June 17, all the first floor desktops have been updated to the proper version of Lockdown Browser.
