NOTE: Please see update below:
This is the result when one try to sign into Blogger when using the Opera browser:
Let's hope Blogger is working on the problem. Never had that problem before.
UPDATE 12 November 2007: You can now sign into blogger.com with Opera.
UPDATE: 13 November, 2007
Got a not so polite comment from a blogger in my post Why you should be using more than one browser. I seldom use Opera since I have 4 browsers, and have plenty of choices. I normally have 3 opened simultaneously, but seldom use Opera as that 3 is sufficient for my use. Anyway, after that blogger's comment, I decided to check this post and also tried to sign into Blogger with Opera again. I found that after signing in, you don't get automatically logged into Dashboard, but have to click a link "click here to continue".
That blogger said Opera is now up to 9.5 now, but my version is 9.24. Contacted that blogger, and now waiting to see if he respond before I update this post further.
