[Newbies] Can't enter class comment?

[Tim Johnson]

Hi,

Fresh 4.2 image.  Opened Browser.  Made a new category.  Made a new class.  Tried to change the class comment but can't.  Can't, can't, can't.  Can you?  For me, it always goes back to "THIS CLASS HAS NO COMMENT!" What is going on?

Thanks,
Tim
