scrollbar problem

["M.N.S.S.K.Pavan Kumar" <pavan gdit iiit net>]

hi,
	I have a clist in a scrolled window. the clist is long and has a
vertical scroll bar. the clist will be updated for every 3 or 4 seconds.
in the meanwhile, the scroll bar can be scrolled. but when update takes
place.. the scroll bar is again moving to the top position. 
	Is there any way to regain the position after updating.
i have tried storing the hadjustment and vadjustment of the scrolled
window and set them after updating. but that is not working.
	thanx
regards
pavan
