I have used this particular computer to add posts to blogspot with no problem. I've also used the wireless network at the hotel I stayed at to add posts, but not this particular computer. The combination, however, appears to be a problem. I could not open my account at all last week - I kept getting a cascade of errors that appeared to be specific to blogspot.
Now I have a workaround and should be able to post normally. Has anyone else had trouble with blogspot recently?
