FYI..if you're having problems with Blogger stating "Unable to open and then aborting" apparently the problem is being caused by the Followers Gadget. Remove the Gadget from your blog and it should function normally again.
I don't usually post solutions on this blog, however, I have noticed I cannot get into MANY blogs because of this problem which included both of my blogs as well. I have tried to comment on others work and have been aborted out, very frustrating. There are also several challenge blogs that I cannot get into.
Once Blogger figures out the problem I plan on adding the Followers Gadget back on to both of my blogs.
Hope this information helps. - Kris
***MORE INFO: If you are also having problems with your Blog opening windows over and over again it apparently is also being caused by this gadget. I would save you the $$ I spent on anti-virus software just to find out that the Followers gadget was the culprit!
