I am building a very large level which takes a long time to load up, creating AI Obstacles is the really long wait. I often find myself pressing Esc when I meant to press Tab on entering the level to change settings.
I know this is my own fault as I don't always pay attention to the keyboard when working and it irks me immensely but perhaps it might be better to have these two a bit further apart so I don't keep doing it, Backspace would work better for level edit, for me at least, I don't know if others have the same problem with it
A funny thing happened on the way to the forum...
