Koo,,,,,if I can take this question,,,,well,,,,,,it generally happens when ones face meets a fist,,,,the shock causes a disruption to the brain as the connections kink and causes it to shut down.

Thats all I know about that!

Seriously,,,a blackout happens to insiders and those in the know around a publiclly traded company when material information that could affect stock price is not out to the public. These people are restricted by the securities overview entity responsible to admin the protocol of the excahnge for fairness. They cant make buys or sells on info that is privy to only themselves!!! Ask Martha S. about her inssue of past! :o)

,,so,,,,best suggestion is smoke 'em if you got 'em,,Koo!! Somtimes me thinks there is a cloud around ya,,,,of smoke that is!!
