I'm sure one of you computer geniuses can help me with this... I've tried everything and can't figure this one out on my own.

Okay, here's the deal. You know when you download certain types of files, it'll ask you if you want to open it or download it? That's what it used to ask for .ZIP files, but I accidently set it to automatically download the files every time. I don't want it to do that... I want it to ask me each time whether I want to save them or open them... but how can I reverse it after I accidently told it one thing? Thanks!
