davidols...I also don't think you have much to worry about.
With so few shares (aprox. 45 million) on issue the shareprice could move strongly on good news. It was just before Easter when the stock traded as high as 95.5c. Should do that again on more good news or a certain newsletter's buy recommendation.
If anyone wanted to manipulate a shareprice up or down this stock would be a good choice (again because of limited shares on issue).
