I just realised that the haloscan comments is openning another pop up window from this opm.blitzed.org website which is banning some IP addresses! I suspect this must be some stupid bug that has attached itself on haloscan as I definitely did not install that. No indication on the haloscan website also about it. If any of you know how to get rid of it, please email me at email@example.com so I can fix the problem.
Pending all this, I have re-activated blogger's comments so please post your comments there. Thanks and hopefully I can resolve this without losing my old comments.
