Wainfleet Posted October 3, 2020 Report Share Posted October 3, 2020 When exploring how to set up a teaching table, sometimes a large rectangular grey window appears , taking up one third of the screen on the left, and I can't find a way of getting rid of it without logging out of BBO and setting up everything again from scratch. Any ideas what I am doing wrong and how to correct it? Thanks Quote Link to comment Share on other sites More sharing options...
