When I want to add a new class sometimes I will open the course record and click the '+' on the first page to add a new class. The screen that opens up then is very difficult to use and I can't get out of it easily. ie: the window is not properly defined, I can't minimize or close it easily. The best way to close it is to tab to the cancel or save button and select them that way - I can't actually click on either of those buttons. I think there may be an issue with it because when I add a class through the separate class menu item it works fine.
I am not the only one who has this issue - could you advise?
