What is error #404
Lately when I open Safari I see the normal web page in the background and then a small dialog box pops up with the Safari logo in the top left corner the the typed web page and under that is the error #404 - I then click on the blue button in the right hand corner and then it goes away and there is my page behind it working fine? How come this comes up?
