I think its an Internet Explorer fault
If the Homepage on IE is displaying Say you have set it to Google or MSN and It comes up fast Or not at all? then an edit of the Home page links is needed (I myself have got 4 somehow

) but only need Google
The other way is to do a clearance of the Web Files cache History files and the Temp files
Plus Go into the Control Panel to the "Add Remove" Programs Folder and scroll down the List until You see Windows Internet Explorer 7(or what ever you have)click on it
Next hit the remove button ...
Message flashes up offering Delete or Repair
choosing repair then OK Starts the overwrite and don't forget the Temp file delet at least
Now go online and see if the Pafes are sowin faster..Retun the Internet explorer if no Joy
and delete the web file cache and the History files whichwill mean a slower page load for a short while as the Pages are kept on File and are Used as a template to update from the Web
What you have is a Page lurking which is a misload and its being "seen" as a Priority and has blocked the queue
No use trying to pick it out of the files and deleting it will take you ages and a big slice of luck even if you are experienced.

So The fastest way is a total delete OK?
