I'm using Gmail, instead of downloading the attachment, I just opened it and edited it. When I closed it, I clicked save. It never said save as what. I've checked Temporary Internet Files. Did I lose the edited document? If not, where can I find it?
It may have been automatically saved to your download folder depending on your download settings. In XP check My Documents\Downloads, on Vista/7 check Downloads under your user directory, OS X and most desktop Linux distros is ~/Downloads.
