Why am I constantly refreshing pages?

For example,

I could be posting this topic here, however if I edited it, and viewed it again, it would appear as before. I would have to press the refresh button to get my edited version. This is constantly happening in other sites and forums also, Im finding myself constantly refreshing to update information ive typed in and stuff. Any ideas? I know this is perhaps something to do with registry or something. I deleted something out of registry in the url folder, to delete my history. Also, I have been messing around with options trying to delete sites. Any information?

Are you using opera?

If it is Opera you'll need to do this:

Click Tools->Preferences->Advanced->History

Check documents = Always

If you're using Internet Explorer 6, use Tools > Internet Options > General > Settings > Check for newer versions of stored pages: Every visit to the page

yeh think thats cured it ! thanks
