Is it possible to have two or more custom CAS screens in my download folder? The way I see it is multiple CAS screens cannot exist in the game at the same time, unless they are chosen to display at random which I see as unlikely. So, yeah, can I have more than one CAS screen at one time?

Moving to Help as this is not a site issue.

You can have one CAS and one YACAS (young adult - for University, if you have it) at a time. You cannot have more than that at once, but you can keep several other ones outside your Downloads folder to switch out as you like. I think there's a program that lets you switch between them somewhere on this site though.
