Qualstar Corp. won a recent proxy battle by a dissident shareholder who pushed to remove the Simi Valley company's board of directors. But Boca Raton-based BKF Capital Group Inc., led by chief executive Steven Bronson, said despite a failed attempt last month to unseat the board, it will continue to push for change at Qualstar. "We are not going away and the issue is not going away until management starts turning the company around and creates value for the shareholders," said Greg Heller, senior vice president with BFK Capital. Heller said the shareholders are weighing their next move, which may be filing a lawsuit that calls into question how the company handled the process of voting for board members at its special meeting on June 20; and setting up a slate of directors to run for the Qualstar board at the next annual shareholders meeting next March.
