Found a bug that's just been a bit annoying, doesnt take time to make it work, but still. I do not know particularly what I do to make it happen, but sometimes the window under the scene (where you assign commands and many things, where it says "scene object".). Every now and then when I play around with the editor, this window disappears, and this whole area is just greyed out. I do however, only have to change over to properties, and back again and it looks like it should.
Don't know if anyone else has met this particular bug.?
