Hello I am having intermittent problems with MacBook Pro Intel Core 2 Duo 2.2GHz with 6GB RAM (yes, six GB) and a Seagate 500MB/7200RPM Snow Leopard OS 10.6.2 Mail will quit when I try to add an attachment If I go to the Finder from another application, the Finder quits and windows disappear. If I select "new finder window" finder repeatedly quits. After 10 or fifteen times (usually I just restart) I can get the finder window to stay open. Using Safari and selecting a file to upload causes Safari to quit. Firefox works fine. I have done a clean install. Problems persist intermittently. Any advice on how I can fix this? Thank you!
