Strange indentation after REFERENCES

[Ehud Kaplan]

I have a Lyx file that was exported to Latex, in order to include 
references (using the .bbl. file). 
With pdflatex it produces a perfect looking pdf file.
When that Latex file is re-imported into Lyx, it produces a pdf file 
that is correct in every way except one:
The entire bibliography (following  REFERENCES) is indented by approx. 
1/3 of a page width.

Any ideas?  I see nothing wrong in either the Latex or the Lyx files.
Thanks,
EK
