It happens so often, you MUST do something about if for your customers to keep their sanity! Too many times I have walked away from my computer, come back thinking my session is still alive. After expending a considerable amount of work, I go to save it. Then I get a message. This time is was "cannot save your work", "Refresh screen". After refreshing my screen I discover that I am not logged in and my work is gone.
THIS IS UNACCEPTABLE!!! At least my bank, the only other online agency I know of that times me out on such a short leash, actually logs me out so that when I come back I know I'm logged out AND DO NOT WASTE MY PRECIOUS TIME!
I'm sorry for yelling, but you are the ONLY online resource I ever have used that does this, and, as you can tell, I'm really upset about it. I pay way too much for this kind of abuse.
