Part of it is that missing leading . in my input - suggest you add some kind of basic user-input parsing which indicates unrecognized input format, and only activates the buttons when the input is 'legal'. I retried with .4-1, it indeed auto-filled x^4-1 in the entry field, but clicking 'factor' still gives same as before, both 'evaluate' and 'factor' widgets go gray, and things hang until I click 'stop'. This is FF on Mac - I suspect you have some Windows-only stuff going on in your JS. Do you have ready access to a non-Win machine?
