[Tugindia] Citations extend beyond page margin

[Himal sharma]

Hi Everybody,

I am having an unusual problem of extended text beyond
right margin. It doesn't happen with the regular text,
but only with the citation. Here is an example.

---
While at the end of the line
the citation like [Bush and Cheney, 
2004], it doesn't break pro-
perly. In fact, the citation
should appear like [Bush and 
Cheney, 2004].
---

Could someone suggest me on how to overcome this
problem. Thanks

himal
