Product license revenue climbed 10% to $143.1 million, while revenue from license updates surged 22% to $109.3 million. Goldman Sachs analyst Sarah Friar attributed the sharp rise in the stock in late trading to a good quarter for the company's presentation server business, which represented 77% of total revenue in fiscal 2006. "That's where they missed last quarter," Friar said in an interview, and there was some fear on Wall Street of a repeat performance . "The bearish case was tied to this segment."
