Sun,
I have turned off, closed, the FAH Control numerous times, just like "X"ing out of a program, and then would go to PROGRAMS and click on the FAH CONTROL and re-start it from there rather than re-boot the whole computer.

You really can't hurt this thing so no need to be afraid of it.
As I said, I shut mine off , (close it) , and then go restart it with no difficulties.
I'd give it a try.
How cold is it where you are btw?
It's 28 here and I am shivering inside a 70 degree house.
