I've just noticed over recent months using IE that there's a growing hiatus between clicking a link and connecting. Becomes even longer when pressing the back button to return to the previous page.
Something to do with all these Twitter, Facebook etc links that need loading to every time a page is opened, perhaps?
Is it just the sheer volume that my connection cannot keep up with?
Not the end of the world - but gets annoying, especially when working on a tight schedule.
