Converting to PDF - problem in bibliography

Hi there.

When_ _ convert my paper into PDF the biblio goes a bit wonky. Where there are hyphenated page numbers eg 23-27, and a URL in the information, for some reason the digits after the hyphen gets dropped down into the same line as the URL.

For example,

Ref in word looks like

"smith, g. 2000. ‘it’s a dog’s life.’ journal of this and that 33 (2):23-27

www.jstorxxxx.com"

But, after converting to PDF, the final page numbers are in the wrong place

"smith, g. 2000. ‘it’s a dog’s life.’ journal of this and that 33 (2):23

  1. www.jstorxxxx.com"

If anyone has any ideas how to stop that, ie how to keep the 23-27 together, I would be grateful to hear them

Thanks.
