We HAVE  one computer that we keep all updates up on.   But we also check the issues we are having against the new program, and if what we need to function is not fixed, then we are not updating the other computers.

What about the inability to backup to a flash drive, unless you first delete the previous backup on that flash drive?

I am not even going to go into the issues, but know that we ARE monitoring the updates, and there are still things not working right.   And now we are "update shy"
