Windows XP: Problem with left clicking ro open Drives in My Computer

Problem with left clicking ro open Drives in My Computer

I have Windows XP Home Edition. I utilize the new XP view of My Computer. I clicked on My Computer (left)
and clicked on the c drive (left) and I would see a listing of the folders on the drive. All of a sudden when I left click on the c drive the search window comes up. I have to right click open on the c drive to see the folders. Is there a way to restore the folders to be viewed with a left click on the c drive icon? This is happening in My Computer on all drives. Thanking you for your help.
