why did mac give me false hope?

Granted... it was a 4 day week, and i only worked on my mac for 2 half days of that time, but none the less, i thought i was actually going to make it through ONE WHOLE week without a crash! .... all i wanted was to add a key frame in flash.... ..... been watching the rainbow wheel of death for ages... i don't want to force quit.... i don't know when i saved last.... sigh...
