I opened the Gmail web-page for logging in. There I filled my username and passport. At that time I did not notice the box "Stay signed in this computer" has been ticked. Without noticing this ticked box, I pressed "Submit" button. So every time I open the Gmail loggin web-page, I automatically log on to my mail account. This I do not want. I want to type my user id and pass-word every time I log on into my Gmail account. I am not a techie! So please help in step by step instruction!!
