Windows 7: oops, this is weird

I was logged in, then went about switching around through different pages & found that I wasn't logged in on others. Do i have to log in at each seperate one?

That shouldn't happen - are you running any cookie blocking software/scripts/browser addons?

I don't know. Would it have anything to do with this blue circle?

That is a tracking protection icon so you're blocking some sites cookies, but it all depends on what you have it set to block.

I vaguely remember doing something to stop the 'googleads' thing that was interfering with my 'back button'.
I'm thinking that I've done something with my IE9 because it certainly is NOT speedy like the commercial implies. I really notice it here at sevenforums with that 'waiting for response' notice. And I'm sorry to say that I don't remember if it's always been slow. Have only had this PC for just short of 3 months & it's a whole new experience with Windows 7 compared to XP.
As I'm sure you can tell from my wording in questions & replies, I am NOT computer literate.

Thank you.

Even tho' I'm stiil working on my browser settings, etc. will go ahead & mark this thread solved, the title isn't descriptive anyway.
