  Hello,
    I'm having trouble trapping IRQ11 or IRQ12 under windows.  I am trying to
 write a device driver.  The problem isn't really with trapping the interrupt.
 I found some sample code that helped me do that.  The problem is that anytime
 that the IRQ line is enabled and I switch focus to anything other than the
 program that uses the driver.  Windows crashes.  I've seen it crash 6 totaly
 different ways, and I'm getting tired of it.  Does anyone have any idea what
 is going on?  Is windows changing the interrupt vector table w/o telling me?
 ANY help will be appreciated.

  Thanks,
     Keith (kdw103@psuvm.psu.edu)
