IE Settings

I've been wondering what the best setting for the IE browser should be for ordinary day to day use.

These are the ones that are found under IE properties in the Temp Int Files settings.

There are 4 options :

1) Every visit to the page
2) Every time IE starts
3) Automatic
4) Never

Anyone got some ideas on what these do and how it affects browse speed etc.

I'm currently using option 2 from today... before I have used option 3 for months... so I'm kinda gonna see if I notice any difference. I have been getting crashing on some websites... this one in particular for some reason, so I was hoping maybe a switch from the auto option may fix this problem as well.
