how to get Clock cursor in place of Hourglass cursor when system is busy in Debian/unstable

["J.S.Sahambi" <jsahambi@iitg.ernet.in>]

I recently updated the system (Debian/unstable) from debian servers. 
When the system is busy the cursor changes to the standard hourglass.

I also installed Debian/unstable from the same server on a new system 
from scratch. In that system the system busy indication is with a new 
Clock cursor. I would like to know how to get the same in my older system.
I think it must be some configuration file that was not updated while 
upgrade.
Can some body have any idea?

Thanks
