First, I think the following problem is a general issue and not limited to a single course. In any way, we are working on 7.3/7.4 courses which are not available in the list.
So, what's the issue? Some of my colleagues are working with a two screen configuration. One of the screens a slighly older model with a 1280x1024 pixel resolution, the other one with a HD resolution. If the move the Pega exercise system to the smaller screen to have access to both, the exercise system and the documentaion, the Pega application will not re-scale properly, so that some not exactly unimportant Buttons like <SAVE> are out of Screen. See attachement. Is there maybe an configuration option to fix this?
