Mail app is using 3GB of memory and 85%-95% of the processes are Mail. It won't quit nice, it has to be force quit every time. It seems to be hung up on updating the "Sent" mail; the spinning gear next to it never stops. I've checked its preferences and everything looks good. If I delete Mail from my Apps, is there someplace I can re-download it? At Apple? Off my SL install disk? I am clueless here.
