I have to agree to the fact that a lot of Indians compulsively have to use 'Refresh' five or six times before or after doing anything on their computer. It's sort of like twiddling your thumbs digitally while you wait for something to happen or maybe like cleaning up everything after you're done. I very rarely do it but sometimes I confess, it's an itch that has to be scratched and so on Ubuntu I end up using F5 every once in a while.
Another reason maybe is because in Wind**s, clicking "Refresh' rearranges the icons neatly. It is something that I honestly miss in Ubuntu. Also, 'Refresh' generally does away with incorrectly drawn windows, or some program that has crashed etc. I'm not really sure what Refresh does though..
