You can't just insert Window off anywhere in the program it has to be in the
beggining, like the first line, or if you have a resource file, the second
line is acceptable, but if you have Window Off way down there, it's not going
to do it's job properly.

Example:

WINDOW #1, "MySplash"
INPUT "";test$
WINDOW #2, "Test2"
INPUT "";test2$
WINDOW OFF
WINDOW #3, "Test3"
INPUT "";test3$

The Command window will not go away, and you may have problems with the
MySplash Window, and Test2 window unless the WINDOW OFF Command is either the
first line in the program or right under the RESOURCES statement (which would
be the first line in the program).
