I am plagued by random behavior from IE8. Increasingly often I click a link in an email and the new tab appears to hang. I usually see the spinning circle that suggests the tab is loading. I somtimes see the title appear, then I can wait forever. Whilst I am waiting I can return to the email, copy the link, paste it into a new tab and SOMTIMES the page will come straight up. Somtimes it won't.
A bit of googling suggested it was the pop-up blocker (Tools | Popup Blocker) so I turned that off. It seemed to get better for a while, but now it's a pain again.
I see the same behaviour if I Wheel click (open in a new tab) a link on a page. Usually, whilst the link is not appearing in a new tab, I can left click the same link (open in same tab) and the link will open instantly. This behaviour suggests to me that it may in some way be related to security, but not in a way that's obvious to me.
Environment - Windows 7 (64bit) - RTM Code from MSDN + IE8. I am running as an Administrator account.
