Hi. Just received my iMac G5 yesterday. I love this thing. I'm never going back to Windows. Still got some questions (perhaps obvious ones)... I hope you guys can help me out. 1. How do I manage file associations? I know I can use Open With, but it's annoying. I have .jpegs that open in Preview but .jpgs open in Photoshop. .ai files open in Preview by default for some reason, and not illustrator. .HTML files open in Dreamweaver instead of Safari... how can I manage this? 2. During sleep, are processes still running? Say I'm transferring or downloading large files or performing some process that takes a long time... will the computer automatically sleep even if that process is running, and will the process stop? 3. Is there any way to stop having to type in my password every time I install something? 4. Thanks.
