[BRLTTY] BrlTTY Braille freezes on Windows7 64-bit with NVDA

[Michael Whapples]

I can say one thing for sure, BrlTTY is still running, the process was still 
shown in the task manager when Braille froze. Although the process was still 
running I don't know whether BrlTTY was still responding.

I don't know much about Windows, but is there an equivalent to the Linux
syslog facility that you could check for reports of segmentation faults? 
This
will tell you if BRLTTY is crashing for some reason, although one would 
expect
your screen reader to complain if it loses its connection to Brlapi.
