Got various CSS issues to resolve at my other WP playground testing site. The theme author Mike suggested that I use Opera. I tried Opera and found that alignment was perfect for the beastblog theme at "WP Playground".
It's OK perhaps to use Opera and FF together for 2 gmail accounts but too bad just found out that Opera doesn't support Goolge's Personalized Page for some reasons. I have since reported that. It would be nice if Opera supports Netvibes or Netvibes quickly make their site good for Opera.
