Wow, this post had me worried – nothing a regular user program does should be able to blue-screen a W2K3 box.  Looking at the description of the program, however, I see that it installs a device driver.  Ok, that makes sense; I device driver *shouldn’t* blue-screen the machine, but it certainly has the *ability* to do so.  I’m guessing it’s a flaw in the device driver that is causing the problem.
