According to Dell Support, some temporary internet files left over by the application programs are supposed to be accessed and cleared via - " Performance and Maitenance" tab under Control Panel.  

 

I can not see this tab. I am not sure if it has anything to do with it, but I am happy with Windows Classic View setting. Anyway, I tried with Windows XP view setting, but still no luck.

 

Appreciate any clues.

 

Thanks.
