Whew! If even one of these things happened to me I would take an axe to my machine in anger and frustration. As a Mac user I do a number of things on a regular basis. Rebuild the desktop once a week. Run Conflict Catcher whenever something new is put into the system. Run Norton disk Doctor at least once a month and optimise the HD. Run Aladdin Spring Clean about every six months to get rid of the huge amounts of junk that accumulates all over the HD. I learnt a valuable life lesson many years ago. My technical Drawing Tutor at school always started his lessons with this mantra, " Never start a new job with a dirty instrument!", how right he was. Now I have opened my big gob the system will freeze up for the rest of the day I expect!. Wishing you all a glitch free heaven on earth.
