Okay, I guess I should have been more specific. I mean Calculator.app, not the widget. The widget works fine. But I want to use Calculator.app do use it's scientific functions, etc. It has no problems calculating things, but when I tell it to quit, it won't, and when I switch it to graphing, it just is a big, blank brushed-metal window that won't change back to the Basic or Scientific calculator, either. Really, I think I need a new Calculator.app. I tried ditching the preference file, and that did nothing. So is it on the Tiger install disc anywhere or could someone please upload it somewhere so that I can have a fresh copy?
