Thanx to Sigurd Magnusson, Peter J. Farrell, who take time to answer the question.
Special Thanx to: Juergen Auer, Ben Curtis and Jalenack (for info about Mac IE5 and Safary) Juergen and Ben was absolutely right - the trouble was in first line (empty), which was generated becouse " newlines immediately after closing PHP compilation markers" in my include files. Thank you Sirs.
