what\'s wrong with my apps? Our ibook is not even a month old and some of the applications have crashed on me the few times that I've used it, particularly iphoto and word. I was running a cd-rom when iphoto crashed but i was using word on its own when it quit unexpectedly. This hasn't happened so far with my g5. Why have my apps been crashing? Is this normal? Any suggestions how this can be avoided?
