Well Dorothy it is kinda like this: JAWS takes a picture of your computer's hardware and some software. When anything changes such as the wind is blowing harder outside, the moon has changed phases or JAWS just feels like it you will be notified that you must again authorize JAWS. Of course you only have 3 keys before you need to communicate with helpful FS and play the "Mother may I?". Now, from time to time my JAWS declares it is running in demo mode and I just re-boot and that seems to solve the problem.

Subject: hardware software dear list having what appeared to be a clean install of jaws on my dell and subsequent crash and visit of a so called dell support jaws would only work in demo mode. a memberof this list said it due to my "thumb print with fs changing, I am wondering just what constitutes a "thumb print? I know clever vips who use Jaws and make their own computers, they do not make laptops the components are too small, now if a Jaws user makes a desktop and adjusts it or makes a few improvements how muchconstitutes a change of thumbprint with fs? wwhich obviously thought a change of draw was my,well what exactly does it think I am using new pc or doing something illegal? The idea of a never changing thumb print means what exactly,can't they ask me first anyway now whole computer is now being reinstalled that will mean more than a thumb print of course What is the smallest change of thumbprint that fs will not get worried about please I am just being curious thanks Dorothy?
