trouble with NS4 objectModel

/*
  Will somebody please tell me why I don\'t get two identical 100px by 100px squares?
  One is fine fine but the other one gets crazy like some inline stuff? i don\'t know?
  This is of course meant to be working in Netscape.

  I\'ve done something similar in Internet Explorer and it works fine!

  I know that my object-handling sucks, maybe that is my problem?
  The only reason i\'ve put stuff inside the layer tags is because
  the scriptet layer wouldn\'t show otherwise - yet another mysteri!
