Dear Aloke,

There were problems with that in earlier development releases of TeXworks (Tw).

You are on Tw 0.2.3 (r.466), while the current development release of
Tw is heading for version 0.4, and currenty on 0.3 (r.749)

Try and see if you can get your  Ubuntu 10.04 package manager to
update your version of TeXworks if that is possible, (or build it form
sources? - have a look at
http://code.google.com/p/texworks/wiki/Building ) and the problem will
most likely go away.

Paul
