the existing levels, some 3000 of them, be tested in the 4.05 version
to see if they will work in it? I believe a couple of levels have had
to be changed to work in 4.05. Also, none of the ltg's will work
properly in 4.04 because of the movable block mask. So if 4.04 is ONLY
being used to write new levels, and these levels will have to be
tested to see if they also work in the upcoming 4.05.......
