Adrenaline Software, a small software company that debuted in 1995 with Adrenaline Numbers & Charts, has announced that it has ceased operations due to difficult current market conditions, as noted on the company’s Web site. In its parting letter, Adrenaline criticizes Apple for not aiding the company in transitioning its flagship product following the demise of OpenDoc, an Apple-developed technology that was leveraged heavily in Adrenaline Numbers & Charts. All current orders of Adrenaline Charts Pro will be filled.
