I have Dell D430 running Windows 7 32-bit, with an Intel 3945ABG wifi adapter and the latest driver from Intel. When I run Chanalyzer with both the wifi card and wi-spy dbx, it crashes. It runs fine if it's only using the wifi card, or only using the Wi Spy. Sometimes it crashes after a couple minutes, sometimes it crashes immediately on launch. This is what the error message says:
