The problem was that we were occasionally getting SCARD_IOCTL_GETSTATUSCHANGEW calls with infinite timeouts, which we would never return from because our status never changes. This is the correct behavior in the short run, but we were ignoring the meaning of SCARD_IOCTL_CANCEL, which tells such long-hanging calls to return with an SCARD_E_CANCELLED return value. This was causing the "Run as different user" window to freeze, because something internally was waiting around for an SCARD_E_CANCELLED that would never come. To fix this, now whenever we get an SCARD_IOCTL_GETSTATUSCHANGEW with an infinite timeout, we add to the corresponding context a DeviceControlResponse that wraps the necessary SCARD_E_CANCELLED return value. Later, when an SCARD_IOCTL_CANCEL is received for that context, we grab the DeviceControlResponse and return it.
