Mouse not working correctly

I can not double click to open a file or folder. I can only open them by
right click and open. I am using a Microsoft trackball mouse. Does anyone
have a solution? I am sure it is a simple one, but I can't find it in help.
Actually I like to blame it on Vista since I hate it!!!!!!!!!!!!!!!!!!!!
Thanks for the help.

My Trackball Explorer worked correctly after a little trip to the Control
panel and Mouse properties. Blame yourself!
