why do macs rebel against real work?

So its been a little while since i've been on a project that requires a "complicated" flash file (i guess complicated to mac is having more that 5 layers in a timeline).... not even 40 minutes into working, i try to move a shape and it crashes on me.

you know i was just getting to a point of not wanting to chuck this thing out the window, and now i realized it's because i haven't really been doing any "real" work on it.... our IT guy left........... no one will save you now mac... NO ONE!
