Recently I have been running into this quite a bit on the sites I usually visit:
Internet Explorer cannot open the Internet site... Operation aborted
And then it began to happen to mine when I was forced to change my address.
After looking through the 'help' section in Blogger, I learnt that it has been happening a bit recently. The easy solution is to remove the followers gadget from the sidebar, then all returns to normal.
It is a shame though, as it means I miss out on reading some of my favourite blogs.
